Hello,
sorry, i really forgot this post
I am able to play again after two weeks of forced withdrawal.
The DVD rom had committed suicide and taken the SH3 disk with it (scratches and cracks - probably not SF-related). OK, got an exchange SH3 game (guarantee - they would not have had to do it, after all the DVD rom destroyed it) and bought a new DVD rom. I get the "unable to access disk" message very seldom now (every 10th time or so). The ability to write CDs with the Ricoh burner still depends on uninstalling Starforce first. I've come to live with it ...
Greetings,
Catfish
