First of all, try to be a little more polite when you disagree with someone. I suppose that everyone here is trying to help the others make a good copy and sometimes different things happens to different computers.
Yes, you are right, the latest version of Alcohol is 188.8.131.5202, not 2820, as I wrote by mistake. But, sorry, Sacred installs and plays with RMPS activated. Actually, that's what happens ...
Without the update (as I read on another forum, until version 1.5) the game plays just fine. After the update the game plays just once and then it presents disk verification error. As I also read, some claim to solve the problem by just restarting the computer, someothers by renaming the alcohol's dll file that is blocked by ProtectCD protection.
I do not know if any of those works for you. But give them a try!
