@ktm1974 - the only thing I can think is your gpxpdata\track.set file. Open it in notepad and it should look like this. If it doesn't you can either change it, or make a new one with hts data and put it in a mods GPxPatch folder.

@madotter - theres 2 options you've done something wrong, or I have :p For me the rims work fine and I haven't seen other problems so you should check your end. Make sure you have clean wads and exes.
