If you open GPxPatch and go to GPxCInfo and then you open the folder symbol below you can select the wanted pitbord.ini-file
wherever it may be stored.
The result will always be 'K:\Grand Prix 4\gpxdata\whatever...'
So the problem is simple the lack of pitboards in the game automatically triggered by the pitbord.ini-file.
On the other hand it works if you put the file into GPxPatch manually although it's already there...
It's like unlocking a door though it's already unlocked
Any ideas what's the problem???
