Then only a few files could cause it :
- cars.wad
- gpi and gph files
- f1gstate.sav
The easiest to check is the last one : make a copy of this file (and f1gstate.bak which is a backup automatically used by the game if first is not found) and delete these 2 files. Launch the game once and try TeamEditor again.
For the other two, it's a bit more tricky and you might as well make a fresh GP4 install instead, then try TeamEditor with each mod you are installing. One of them is surely the cause of this.
