ltr-40125S problem

Hi! I’m having a problem with my ltr-40125S. It won’t read my discs, or write for that matter. It seems rather dead, but is still present in device manager, and i’ve tried to reinstall it several times. I also got hold of a new FW version at liteonit.com, but this didn’t help either. Any ideas?

A friend of mine suggested it had something to do with DeamonTools, because he had experienced the same thing a while back.
