Windows .exe Monster 1.0.9 crashing in Mystcraft world

[Lithuex]

1.0.9 monster version
Last thing I did was log off in a mystcraft world. I now get these errors:

Sorry for the puush , pastebin gets exceeded in file size.

Here's the crashlog:
http://puu.sh/6T9nF.txt
It's a server crash log, so obviously it's something to do with the internal server. I'm guessing it's a corrupted block but I don't really understand java too much.

Sorry, here's extra format

Operating System, bit type: Win 7 64 bit
Java version/update, bit type: Java 7 update 51 64 bit
Launcher version: 1.3.4
Completed the troubleshooting guide (y/n): y
Console log, pastebin.com link: See above
Description of the problem:See above

Can anyone discern the problem here?

It looks like the dimension ID for the Mystcraft age you went to was 2?

What I'm going to suggest is to open your world in MCEdit and move your player location back to the Overworld. That should hopefully allow you to start up the world again. Oh, and back up your world first, just in case!

As an aside, it also looks like you have two rogue item entities with no items associated with them. I honestly have no idea what that means or how to fix it though.

Yes, the age was 2. I'll go and try that now.

Well I did the "go to player" function on MCedit and it said the level was completely empty. Does MCedit count in all the blocks from FTB? I'm having trouble finding my house.

I think it may have genned an entirely new world.

Well I apparently had backups of my world so I just used one of those. It did seem to generate a new world unfortunately. Thanks anyway.

I would suggest you also take a closer look at your JVM arguments. Some of them are double, and I think that the server might like the -Xmx to be a little higher, like 3072M.
