I know it's stated time & again there is no DMR on the games GOG sells, but I have to be very sure. I own an original DVD copy of the game Sniper Elite: Berlin 1945. I played it a lot on my old WinXP machine. When I tried reinstalling it on my new Win7x64 laptop, it finished the install telling me I had to reboot to complete, showing the logo for some copy protection with 'Star' in the title, I can't remember exactly. When it rebooted, the laptop reset itself to factory defaults, erasing all my installed software & files. I HAD taken a backup, on 4 DVDs, but I found the first DVD was unreadable...
In short, I want to make absolutely, positively certain your GOG copy does not have this security on it. Can you assure me of this?

StarForce, the DRM was called. And I have double confirmation, and email from GOG, so I'm happy now.

And, by the way, it runs very well indeed, with no StarForce or any other DRM!
