Windows .exe Direwolf20 Modpack V. 1.1.1 Won't Launch

[Pergamon256]

When I try to install the DW20 Modpack Version 1.1.1, it downloads but doesn't launch, and I get this log: http://pastebin.com/rrYkaUyf

Thanks for your answers in advance

Anything else? I did not see anything that stuck out as problematic in the log you provided. Can you launch other packs, and have you tried force updating?

Pergamon, I had that problem. You need to find the folder the modpack makes. It can't acess the files for some reason unless it can detect them. I had them on my desktop and I tried to move them and that happened, as soon as I moved them back it started working. (Although I now have a different problem)

Thanks so much, aaronfranke! Force Updating works...I'm fairly new to FTB so I didn't think to check the launcher for a Force Update option.
