This looks like an old thread so the problem may be solved today. Cserebogar, could you confirm if you're still having these issues? Other people are still voting for this open thread and I'm not sure if they really have the same issue or have followed the instructions for troubleshooting like you say you have.

To others: please follow the instructions in the article Basic troubleshooting if you have similar problems to the ones reported here. It will take care of the issues for you.
