Thanks for the replies, fellas.
This is not the first time that NTL have inadvertantly ruined my day, heh.
To be honest, I'd rather sack off the whole idea of a network game than uninstall etc as I have loads of graphics stuff in there that took me ages to compile plus several saved game. I dont have a blank CD on me either. If needs must I'll copy them in to a back-up folder and get on with it.
What I will do now is load it up and uncheck the run as server. I didnt know that this would still be activated after I had exited and then attempted an old game.
All I wanna do now is just play the game on my own. My bro freaked when I told him this morning that I had 'destroyed champ man'.
Cheers again mates
