Your whole JVM (java virtual machine) has crashed. Unfortunately there isn't much I can do, because the error lies out of the field of my influence. What I can suggest though is the following:
 * Restart your computer. Something could be stuck somewhere!
 * Download the latest loader here: http://emps-world.net/Emps-World.jar
 * Make sure that your Java is up to date


EDIT: Does this error occur in special areas? Or is it completely random. A huge stream of errors 'could' cause the JVM to crash, although that's very unlikely for Emps-World. I've never experienced such a bug in the client.

It actually wasnt random. I opened depoist box and it crashed

Does the client always crash when you open the deposit box, the bank interface?

Didnt tried now. I will reply later bout that
