hey, i keep getting problems with opening the game, i press the start button, then it says its running but doesnt open! can anyone help at all??

I have the cd, but it won't start. any suggestions to fix this problem?

I recently had to reset my pc and reinstalled all apps after. Also this game... IT WORKS!! Already played first 3 missions and no error happened! I believe devs jumped back in here to remove errors regarding cd key missing or whatever.

There is no other program active on my laptop. It's still a very new laptop and when I try to start the game I get the screen with the code I need, but then nothing happens and the play button turns green again. The game is not started. So I can't play it. I have tried to start it over and over agai, but nothing happens... I have bought this game some years ago, but actually never played it. Now I wanted to play it, but it won't work......

I know that this is an older game, so obviously not expecting spectacular graphics. I am running a midrange graphics card, GTX 750 ti, but the game won't let me choose the highest settings. Any suggestions or a possible user patch that has fixed this issue?...
