FTB 1.5.2 start up crash. What's the source?

[Barend]

Hello there

I have been using the FTB 1.5.2 (ngt) for a while now. I started it today and suddenly I get this crash report (see attachment).
I have tried starting it again, and I have also rebooted my pc (didn't work).

Can anyone tell me what the source of the problem is? I am frankly not familiar enough with analysing crash reports.

EDIT: pastebin for those who prefer it: http://pastebin.com/PET0Rfym

Edit: I should add it happened the first time I started FTB after there was a sudden power outage while I was playing FTB 1.5.2

Thank you

​

ps: I know it says unstable but the crash came quite suddenly, as I could still normally play yesterday (and there have been no updates)

For anyone interested in the issue:

I managed to solve it by installing 1.5.2 ngt on my other pc (which had never had that specific pack) and it worked on that pc. Then I copied only a few things from my save from my pc that has the crash (enough data to keep me going, so not everything) and that seemed to work too. Then I copied EVERYTHING from the pc that worked to my pc with the crash and it worked again.
