Thanks for your quick reply Raze!
Ok so the dvd is working on my other computer; there can't be a problem with the dvd itself. I cleaned the dvd (there were only 3 little dust bits, no fingerprints or what so ever). Tried to blow the lens/inside of the player aswell. Started pc with cd in it, without it.. Tried open/close it like 20 times now but nothing works..
It doesn't say anything. It's just an empty disk (when i press 'explore', it's empty). When I press open, it does nothing. When I load the dvd, it makes a lot of noise like it's trying really hard, but it doesn't do anything!
So then I thought about dirty lens/dvd problem as well, so I put in a dvd of paint shop pro -> works. Dvd of divine divinity -> works.. Seems to be this dvd only..!
I tried the save mode. Well that gave the same outcome. No recognizion.. But, also the whole system went crazy, it said smth like 'my computer isn't working/reacting'.. Tried it twice, but no difference the 2nd time...
