This sounds like a job for Wyldanimal! Seems to me tho that you might need to edit the registry. If you are comfortable doing this, you could try checking your model folder path.
Sorry but my screencap software doesn't want to copy this right now but here's what my regedit stuff looks like:
HKEY_CURRENT_USER
Software
Totem
vghd
System
ModelsPath REG_SZ E:\Vgirls\models\
This last part, you can edit to point to your precise model folder.
Hope that helps :/
