Windows .jar Crash On Startup

[Fighting_Mineral]

FTB Launcher version: v1.2.4​

Minecraft Version: 1.4.7​

Java version: Not exactly sure which one your looking for, but I have both jre7 and jdk1.7.0_15​

Detailed description of the issue / how can the issue be recreated: I tried getting on 1.1.0 Ultimate today, and everytime I try, it crashes while its loading. I've had no problem getting on before today. It gets to the white Mojang screen, freezes up for a second, then crashes.​

Error logs: I'm not sure if this is what your talking about for error logs, but I have attached the crash report as a file.​

If someone could help me out, it'd be much appreciated. Thank you.​

Could you post the first few lines of your portalgun config file here?

The config can be found in modpack -> minecraft -> config -> portalgun.cfg
