MadMonkey:

Yep. It's the 3.5.2  -  but strange: i downgraded to 3.0 with an older CD and now its updated to 3.5.2 again and works fine!
Two other friends experienced the same and it was solved in the same way... .

Rabittoid: well, in the preferences there was nothing in (no proxy).

I was just curious cause this happened to others too if that was a well-known bug but doesn´t seem to be so ;-)
