You're trying to run a 1.6.4 mod on 1.7.10. Remove that mod. The thread only states it's compatible with 1.6.4, so it won't work with 1.7.10. I already said that mod won't work with 1.7.10, so why did you reinstall it?

EDIT: Where are you getting these mods from? Both versions are seriously outdated, that Portal Gun is for 1.5, and I assume the Util is also for 1.5 considering it's the first on the downloads list. Go to here and download the correct mod versions.

Well...I solved the problem.I drop the hole .zip file in and it worked.

Now I'm getting another problem:when the game start,it just disappear in a few seconds without crash report.(.zip file,not folder anymore).zip file just work with the old ichun util.Any help???

Logs. No, there are logs. There are ALWAYS logs (at least 2: FML log, launcher's log). Post one of them. Use spoilers.

if you are answering the first one,i posted alot.if you answering the zip one,i swear there are no crash log when it disappear.i checked it,so dont ask.

I probably know why the game crash.The mod using zip file crashes the game at pre-intialization.
