I'm not paying 45 euro to play a game I can't make a backup for myself from...
Larian: go with SafeDisc (above version 3.15) next time. Most CD burners can't produce working backup copies to disc, which is understandable 'cause of piracy, yet SafeDisc allows me to use a virtual drive so I can protect the original disc.
Divine Divinity was a great game, but I'll buy Sacred instead.
