G.D.B files

[Darryl Webb]

When hosting certain tracks i can join players host but they cant join mine because of G.D.B mismatch,i have tried re-installs different d\loads etc, i am still not sure what G.D.B files are? Is there a fix of for these files? I have spent months getting ports open and running only to be beaten on most circuits (not all) by G.d.b mismatch. There is hundreds of super circuits out there that people must have worked real hard on, and it seems a waste not to be able to run them..Its race 07 im running the tracks work within my game, i can join a hosted game, i can host games, its just certain tracks that wont host at my end.
