OP Flashpoint NoCD doesnt work
 

I got the No CD key from Game Copy World. But I can`t play the campaign game! After I finished a part of the campaign the game kicks me back to the entry screen???!!! First i could play it up to the 7th oder 8th mission, now it stops after the 4th!! Any ideas?

OPF is quite buggy. You could use a cheat, which allows you to play all levels.
