Most Modpacks Crashing on Launch

  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

Title:
Most Modpacks Crashing on Launch
Launcher Version:
1.4.11
Modpack:
Obscurity
Modpack Version:
1.1.16
Log Link:
Details of the issue:
FTBLauncherLog: http://pastebin.com/7CdaLrVf Upon starting a modpack, one of a few things will happen. Either minecraft will start but then crash upon building the mods, or it will just crash and send me back to the launcher before minecraft opens. The pastebin I have left is Obscurity, but that is not the only modpack I'm having issues with. I tried completely reinstalling FTB (using the guide on the forums), yet I am still having this issue. This is a recent thing, I've never really had this issue in the past. I also have not had any hardware changes recently. Some help would be greatly appreciated.

Have you recently updated your graphics drivers? Do you have more than 1 version of Java installed? Try removing excess Java versions and updating your graphics drivers. (Reinstall Java while you are at it!)
