the models won't export.

Maya session start failed: Create process failed: The specified file could not be found.

Can't open/read granny file for model \de_latnik.xdb#xpointer(\Model)
What should I do?

I messed up somewhere with the names. Maybe the Maya version is incorrect – that seems strange, but it really looks like both versions are 6.0, and with one of them, I can successfully insert the model, but with the other, I can't. Please provide a screenshot of the startup log.
