Nascar 2003 Season Cup90 mod problem!

[Patrik]

Hi! Just installed the Cup90 mod for NR2003. Went into the game, the cars looked amazing, picked a car, went to 'Testing Session' but when i click 'Continue' after choosing track I get the message 'Could not load the track'.

What's the problem here?

EDIT: It worked perfectly before I installed the mod, but I can't see what has gone wrong.

EDIT: Figured it out...
