When Igo to start editor it won't launch it just hangs with the splash screen, no error messages have popped up.
I can play the game no probs there.
Any suggestions????

Could you give us a little more info about your system?

I think you havent got enough RAM (memory), because to me happened same when I tried to run it on my two laptops, when on my pc run it great. Can you post info about your hardware config + operating system ?
If you got enough RAM (2gb and more), it could be issue of your sound card, in case you got some Soundmax card.
