Yes, it was 540M, sorry for the typo.

Shorty, I've tried everything you said, nothing worked, except NO shadow. But... I Did mention this quite clear several times in the thread. It acts as if some shadow engulfs the object and when shadows are on everything is dark. IF shadow are off, the object lights up. I'll get a new computer soon, hope this wont happen there also. But it's really annoying.
