Blender Crash without any Comment...

Hi there, hope its the right Forum to ask this…

If i started blender.exe a few days ago, it does his job wonderfull.
But since 2 days it wont start again. Dont know why but only on my Desktop PC. On my notebook blender works fine.

If i start blender.exe the console-thing popping up and just disappears, without any comment.

So i post here the drwtsn32.log entry of this “event”.

It’s a german installation, i hope it doesnt matter…

hm, perhaps the new ati-catalyst 7.7 is a problem?
I deinstalled it and blender now runs again without problems…

Any experience about this?
