I'd have guessed that it's rather got something to do with vue not finding the related files anymore, I have had that problem after moving my texture file folder to another drive. I also never thought about the temporary files, I would have assumed these are created on the system drive where the operating system or vue is installed. Does vue create the temp files on the drive where the libraries are stored? Maybe thats a bug or so, as it doesnt make much sense to me...
