Blender 2.58 Crashing on start

Hello. I’ve been using blender 2.58 normally day or two and suddenly it crashes. Now, it’s won’t even start up. When i’m trying to launch application, it gives me error message like that:

Tried different build from graphicall, and official build too. It seems like it’s python problem, but reinstalling it didn’t solve problem

Any help?

Also, when i trying render heavy scene in 2.57 with 5 or so lights it crashes too, why? I’m on Windows XP.
