Direwolf20 Server crash when player joins

[medievalcow]

Hi everyone!
I've tried everything including reinstalling minecraft, redownloading FTB launcher, deleting local files, changing worlds, reinstalling java...
I'm running a server just for myself and my girlfriend and brother on my computer, was running fine for the last week up until today, when i get the following crash report no matter who tries to join.

does anybody know what to do to fix this?
Also, my bat file to launch it is suddenly not working as well. this is the contents of that:

Any help would be greatly appreciated
Thanks in advance!

This appears to be a problem with an Easter Egg from Railcraft. You need to edit the config referenced in this post. You may also have to go into peaceful at first to get rid of the mobs.

Thanks for the reply.
After posting, I saw many other annoyed server hosts having the same problem, and changed my server time to saturday the 2nd of november. I have been running for 5 minutes now and not a problem!
