Windows .jar Problem while loading packs

[Rafael Amorim]

Hey guys, I can't seem to open any new packs. So I select 6Gb of RAM to use as FTB, choose the DireWolf20 pack, download all good, but when it 'try' to start, it just shuts down the launcher, and opens again.

My Log is the following:

P.S: I googled it, can't seem to find any answer.

[INFO] [STDERR] org.lwjgl.LWJGLException: Pixel format not accelerated
...
[INFO] [STDOUT] A detailed walkthrough of the error, its code path and all known details is as follows:
[INFO] [STDOUT] -- Head --
[INFO] [STDOUT] Stacktrace:
[INFO] [STDOUT] at org.lwjgl.opengl.WindowsPeerInfo.nChoosePixelFormat(Native Method)

LWJGL is having some funky issue with pixels. It might be that you need to upgrade your graphics drivers, let me know if you don't know how to do this.

So, I did that, now I have this problem: http://pastebin.com/dgmvcLva

It automatically closes the FTB window and doesn't do anything.

Try disabling your antivirus temporarily.

That fixed the login issue, not sure why it's still crashing. Try deleting your ftb folder in your appdata folder. You can get there by typing %appdata% in the start menu. You'll have to re-enter all settings and your login details though.
