Help With ToCA Race Driver 2

[Brodel]

I have Toca Race driver 2 on DVD, when it gets to the point where I need to enter the CD key it starts to check the disk and takes about 10minutes before it gets to the end and then says the key is invalid.

If I enter a different key that is wrong it tells me it's invalid in about 2 seconds, but with the right one the DVD it takes ages before it says it's invalid.

I have tried patching it and it didnt work and have tried all the no cd fixes I can find online and none of those work either.

Does anyone know what it might be? It's really annoying because I have the DVD right here with the right key etc it just refuses to accept it.

Thanks.
