WE had 1.4.7 working really well. Son wanted to update to 1.5.1 and now I can't get Forge to work. Hence I cant get a few fun mods (Build craft, Flans, Archeology) to run and he is really bummed. Here are the steps I have taken and the error file text. Please help a struggling dad.

Updated to MC 1.5.1 on Mac
added in order Too Many Items, Optifine and REI minimap. Tested each as I went they were fine. Made back up mine craft.jar. Then added FML 1.5.1 universal. MC crashed. copied log file text below:

Starwarsmaniac2, if you would give me a list of every mod you want to use with Minecraft 1.5.1, I will write up some detailed instructions on how to get everything working properly, and add some screenshots if it would help.

I have a nephew who absolutely loves Minecraft, but he's too young to understand how mod installation works, so I do that for him over TeamViewer (remote desktop program). Your situation kind of reminds me of my situation, so I'd be glad to help in any way I can.

You have to completely restart and reinstall minecraft forge and your mods.
always download the newest minecraft forge (universal, unless a mod says use a specific one, most don't though.)

1)start with a clean installed minecraft 1.5.1 NO MODS OR FORGE. (basically delete everything and re-install game)

youtube.com for youtube
http://files.minecraftforge.net/ for minecraft forge. always get the newest universal version for the version of minecraft you are using.

2) redownload all yours mods for Minecraft 1.5.1 version of minecraft (will have to look up the mods one at a time using google)
SOME MODS dont have a 1.5.1 VERSION. meaning there is no way to play that mod on version 1.5.1. ALWAYS LOOK for installation instruction for each mod you download. i personally copy and past installion instructions as soon as i download a mod for 1.4.7 and 1.5.1

DON'T DO THIS!

I'm not saying not to start with a fresh Minecraft 1.5.1, but there are a few files and folders in your Minecraft directory that you don't want to delete.

Thank you so much. I have been on the road this week for work so haven't had a chance to reply until now. Here are the list of mods he wants: Buildcraft, industrial craft, Optifine, too many items, rei’s minimap, galacticraft, flans mod & flans modern weapons, camping mod.
