I am having a similar problem with the two tracks I tried to install yesterday
Watkins Glen (long) and Indy 500 - both versions for hardware.
When I click DRIVE my XP machine crashes back to desktop. I'm running GP3 2000 with the decrypted no cd and I do have GPxpatch.
As instructed I unzipped the jam files into GP3jamsh after creating a Watkins folder.
I then placed the watkin.dat in the \curcuits folder.
I went to GPxpatch and selected the 17th slot for the watkins file - the Indy file in slot 1.
The game seems to recognize the change in the menu but when I click DRIVE it's a crash back to my desktop.
What am I missing?
Thanks,
Tim
