Bug? Starnge CTD error

Hi

I get strange Crash To the Desktop with BGE.

The second BGE start during the Blender session cause the CTD.

This is the case even with freshly installed Blender default ‘untitled.blend’ file…

What could be the reason?

Win XPsp3 32-bit
CPU 2.5GHz
4G RAM
GF 9800 GTX+

Official 2.47

I get problems with my RealPlayer install sometimes or Internet Explorer and sometimes they interfere with other programs including blender
