Please please help 'launcher has stopped working'

The game won't start. I've tried everything so far. I'm running Norton and turned it off - didn't start. Updated my drivers - didn't start. Just so frustrated.
I keep getting 'launcher has stopped working' every time.
I've turned off the comp, re put the disk back in, all that stuff and it still says 'launcher has stopped working'.
What do I do? Or how can I get hold of someone to help me through all this.
It won't launch offline either.
Please, please, please help.
