what was the problem? something like "not able to run in 1280x1024" ?

Many problems. We tried like 15 different systems, sometimes the run ended without any result, sometimes it cannot be ran (freeze on loading screen), sometimes it was that 1280*1024 error (although we were using 1920x1080 screenies =P). Anyway, it's done now ^^

How did you solve the problems then ?

I still have some probleme to launch Unigine, even if it's not on GMA HD 3000

No idea, but we're keeping the hard drive in a safe so we can use it again later =P
