Have you resolved the issue?
Let's see.... runtime errors are usually due to .net frameworks, try installing

Is your wizard in an academy? There was an SRO bug a while ago that crashed the game because of accumlated buffs.. dunno if that might be the issue.
Maybe you can send a bug report to joymax with your character name and server, asking them to move your character, that could help I think.
