You have mo'creatures installed, but not custom mobspawner, or you have the improper version of customspawner.
If that doesn't help then replicate the error and give me the console log, which you can get by going to the console window (the one with a lot of colorful text in it) and click the generate crash report button, and post the pastebin link or the actual log in a spoiler. What you posted is the FML log, which also helped.
I have come across an odd problem, whenever i go to make an instance that is no on the default list but uses MCRewind, and it just doesn't work. I really want to play some alpha. Here is the log:

I went ahead and tried it myself, and I am having the same exact crash. The only idea i could have is wait for MCRewind or multiMC to update. Sorry. :/ It's either a bug in multiMC or a bug in mcrewind.

could it possibly be the "_" character in the Java code line? your instance folder is "\users\Deadlywere\" but the java code says: ... MultiMCLauncher.jar "_Deadlywere"....

The underscore I believe is simply a placeholder for space. Also, since it is in a string, it shouldn't matter. That string is actually the player's screen name.

No, thats my minecraft username, so it should be like that
This won't work on my computer even for vanilla. I have no idea why.
abracadabra, alakazam! Your multiMC is magically working again! (seriously though, please post some more information other than it doesn't work, and a crashlog)
I seem to be having troubles whenever I launch a MCRewind instance (pretty much any version before full release 1.2, but with a few others...) , and I can't seem to figure out why. I'll post the console log and the crash log.

Yeah, if you had read an earlier post, you would see that this was already reported. MCRewind seems to be rather borked right now. :/
TL;DR: Forkk is back from vacation and is back to work. he is working on fixing synctron, but is unfortunately not working on multiMC at this time. He does believe that others that help out with updating are working on an update, and the current ETA is soontm
Now that Forge and Optifine are starting another war about modding the jar directly (if you use any version of Forge higher than 779, and try to install Optifine in the jar like it should FML will state that the jar is modded and prevent the game from starting damn cpw is sometimes crazy...), I hope for a release of MultiMC soon,

I had not heard about this (but it doesn't surprise me)... this sucks because two of my favorite mods (optifine and autoswitch) require something to be added to the jar, and have always worked fine with forge in the past (if you installed in the proper order).

Frankly, while I disagree with cpw on some things, I agree with him here: if you have a decent launcher, the jars do not need to be altered.
For a while, I used Magic Launcher; that was exactly how it worked. It changed how classes were looked up / loaded, such that instead of looking for a class in the single jar file, it would find that class in a list of mod zips. Result: Instead of pre-patching the jar file, it was effectively patched at run time. No alterations to the jars.
Between the lack of support for coremods, and the need to work with the FTB launcher for private packs -- which wants a multi-MC compatible package to work with -- I had to switch from ML to MMC.
(In regard to a mod that gives realistic animal genetics):
Would you really rather have bees that make diamonds and oil with magical genetic blocks?
... did I really ask that?
I think I know why this war was started after all after reading the cpw twitter account, it seems that the new Minecraft Launcher bring a new way for programmers to load up anything without modding the .jar file at all, you need to be an experienced java Minecraft programmer to notice this kind of thing I guess... Perhaps this war will end sooner than expected

please fix
https://discord.gg/0kvhqyfryyjfO7qY
whenever i try to run it i am told it needs to be updated t0 version 89
when it finishes updating it just closes, and when i open it again it informs me again that i need to update
if i try to run the instance i want to use without updating the console works for a bit and i get this: http://paste.ubuntu.com/5854242/
any help would be appreciated, i'm a bit lost
oh and, i checked and my mac is 64 bit
2.66GHz Intel Core 2 Duo
8 GB 1067 MHz DDR3
No, thats my minecraft username, so it should be like that
abracadabra, alakazam! Your multiMC is magically working again! (seriously though, please post some more information other than it doesn't work, and a crashlog)
try right clicking an instance and choosing a new LWJGL version.
As for the updating goes, try downloading a fresh copy of multiMC and using that. It should work just fine.
