That sounds a little different. Make sure you are running the shortcut
that GTR installed in the F1 2002 directory. I'm not sure if it will
work if you just run GTR.exe directly. Anyway, in my case I had two
executables in there before, an F1_2002.exe and an F1_2002_noCD.exe.
Normally I ran the noCD exe, but I saved the other one in case a future
patch required it. When you run the shortcut for GTR it runs
GTR2002.exe, which apparently then runs F1_2002.exe with some command
line arguments to get it started correctly. So in my case it was
running the original file, which required the CD. So I changed the name
of F1_2002.exe to F1_2002.exe.0 and then changed the name of
F1_2002_noCD.exe to F1_2002.exe, so that now the GTR program will run my
no CD exe instead. Works fine. Except this looks like a really good
way to lose a lot of sleep. ;o)
