Car is invisible after changing the model

[BMXreifen]

Hey, i was changing the model of a s15 to add new lights but after saving it as a kn5 in ksEditor it shows up invisible in Content Manager. I don't think the model itself is the problem, because it shows up perfectly in 3dSimED3. So the question: how do i make it visible?

3dsimed3 is not really a recommended tool for AC, could be pretty much anything wrong with it and it would still show the model (scale 1000 times off, objects all set to use a transparent material, etc.)

Thx for your answer, because of that i looked into the file again and realized that my car was way off to the side xd
