I installed gp3 with the patch 1.13. After, i installed gpxpatch 3.92, but when i started the game doesn't make changes in GP3. I reinstalled gpxpatch and nothing, what i do?
Have you enabled the changes you desire in GPX_Patch? GPX cannot be copied, it must be re-installed. You may have to set the compatibility of GP3.exe for XP if you are using Vista or W7. It is probably better to do a full installation again, then you will have the registry entries. Once you have an out of the box installation up and running, then copy in your mods.
