vizard cal3d import failure

[krimble]

I use the cal3d exporter for Maya8.5

I've exported all the parts (skeleton, meshes, textures), created a configFile. It was all going very smooth, but when I loaded the configFile into Vizard and ran the script, a error message appeared.

cal3d : Invalid handle as argument in skeleton.cpp(103)
Model::create: ERROR: Can't create a m_model. Most probable reason is that the core doesn't have any data.

What's that??
There're no mistakes in the configFile, I've checked it 10 times! When I open the csf file with a texteditor, I get some text, so there's data in the file...

Please, it saves me so much time when I don't have to export it in 3dsmax.

thanks..
