Server crashes on startup

[AllKnowingSage]

Hello!
This is my first time posting on this forum, but I host a small server for me and some friends that I keep on a separate computer that is on all the time so everybody can log on whenever they want, the power went out and now my server crashes every time I try to start it up.

This is the pastebin for the crash report

I don't have very much experience with reading these reports, but I tried replacing all of the mod folders themselves (in a copy of course) to see if that is where the problem is, but that didn't fix the problem either.

Any and all help would be much appreciated!

Well. I am afraid I must be the bearer of grim news... Your world got corrupted Power outlets are dangerous, both for hardware and software. Your server had data loaded up, and because of the power outlet it got corrupted.
You might be able to find a tutorial on how to remove corrupted parts of your world... however, since there was a power outlet, it's very possible your whole map got corrupted.
The best thing you can do is use a backup. You do have a backup, right? If you don't, you will have to make a new world, delete the old one, and this time regularly save it...

Sad day for me, thanks for the response, I'll look up a tutorial, but unfortunately the latest save I have is from quite a while ago, but if I'm unsuccessful with the tutorial, part of the fun is starting over right? Anyway, thanks again and may the winds always be at your back!
