if you have VBO's enabled in video settings, turn it off. your graphics chip might not VBO's.

no, in minecraft 1.7.10 there is no VBO

ok. hmmmm.... what were you doing before the 1st crash happend?

I was trying to put the mods into a flash and give to my friend so we can play together but our (his too) minecrafts crashed

and there were no problems when I was playing single

hmmm. what's the log?
not the crash log, the minecraft launcher log

edit profile, click launcher visibility, make it "stay open"

it'll let me see the problem

Ok I did it

What Now?

I am not using mods on forge without forge it crashes without launching

load up minecraft, do what you were doing to make it crash, and copy and paste the user log. (not the launcher log)

When I launch my minecraft it crashes but when I use forge (with no mods) it launches then I try to open my singleplayer world it crashes

Backup your save and try deleting "usercache.json".

ok, but where is that "usercache.json".

In the save file folders ... otherwise I wouldn't be asking you to back them up.

Thanks it worked
