Title: Encountered an unexpected exception NoClassDefFoundError java.lang.NoClassDef

Version: 3.1.2

OS: Windows Vista Home Basic SP2, 3GB RAM, 32-bit

Java Version: Version 7 Update 45

Description of Problem:

My server froze, and I couldn't type "Stop" in it like I usually do when something happens to it, like if something's bugged. But since I couldn't write anything in the server I opened the task manager for windows and ended the process instead, and now I get this error message and the server crashes and doesn't load properly.

Has anyone encountered such a crash before and might know how to fix it? I've done the usual stuff with rebooting my computer, deleting the "railcraft.dat" file and so on. But this is an error I haven't seen before and I guess it takes some other solution.

So if anyone has a clue of what to do, please help!

Cheers.
