Game will not load or chashes

If I open the game in steam I get the loading sign (circle going around and around) and A) can't click anything but the keyboard still works (I can un-pause and re-pause VLC) and I have to open the task manger and tab/space my way to close it or B) I get a black screen and as soon as I click it turns white and I'm asked to wait or close the program.

If I run it from the folder I can get it load till the bar is near the end and then quits and reloads leading to A or telling me that it can't run the game. It's all ready running

.

I know it worked years ago coz I got up to lvl 3 AND I know it works coz my brother is playing it now with no problems (as in as I posted this he started it up just fine)
