I am probably the millionth person asking about this; I looked it up in google, like I was advised, and did what I could. However, I am unfamiliar with java enough to not know what exactly is wrong. I will post what I think is the problem, what it is telling me, and what I have done...
it tells me to open the Log File; It's while FML is running its initial mini-window before Minecraft even loads. Here is a screen shot, uploaded for this post. I open the log file, and here is the transcription of it:

What I have attempted, after looking up in google how to fix a Fatal Error with FML, is go into the FTB settings and i pushed my RAM down to 500mb, just to be safe. Same error. I tried downloading some jar files that someone else said were missing from the lib folder, (they are asm-all-4.0.jar, guava-12.01.jar, and argo-2.24.jar), because "FML is probably having difficulty accessing and downloading those files on its own", still same error? Keep in mind, I don't even understand what the error actually is, because I am unfamiliar with java past the point of simple scripts I used to use with HTML when I was a kid.
Please help; if there is any more information that is needed I will help you help me best that I can :)[DOUBLEPOST=1384342475][/DOUBLEPOST]Also, should be noted that this is my first time ever trying to play FTB. I've heard to many good things about it, and would hear my friends playing it together on their server while in skype calls and it sounded fun, so.... yeah I am a total FTB newbie. Haha.

The files were probably missing as well. The error you have now is caused by the exclamation point (!) in the folder name. Please follow the recommended install guide again to fix this. You might want to keep a backup copy of the two files you manually downloaded in case you are missing the files when you reinstall.
