Blender Kart exporter error

So I installed all the componants without problems into Blender 3D, made a quick WIP kart and exported it.
All was fine, but since it was WIP (and still is: no driver XD) I went back and added a UV map (.jpeg with 512 x 512 dimensions).
Then when I tried exporting this error popped up in terminal:
I removed the texture UV map and the same happend.
Any solutions?
