Make sure you let CSM and Grand Prix 4 pass throught your Windows OS firewall, i think that might be your problem, i tried to download the 1988 mod into gp4 and when i started the game the 2001 cars were still there, but with the 1988 tyres for some reason:
- I uninstalled gp4 gpxpatch and csm, and downloaded all of these again
- I gave gp4 and csm firewall permissions
- I downloaded the decrypted exe from gp4db and pasted it into my Grand Prix 4 folder
- I started to install the 1988 Mod again and it went just fine
If this doesn't work i don't know what might be the problem.
