Hi there... I got it working. I initially thougt that update will lose the ability play backup games.... but since I updated I got new HBC too and all the necessary files... all old was erased and I mean 100%-from 4,0 to 4,3. That did the trick I think... Now even the Call of Duty black ops can be played. This is why I broke my system setup at the first place. I tried to get Black Ops to work and it got out of hand. Thanks for Your advice !!!
