Import from USB turntable

I just recently updated my iTunes to latest version (11.0.5 (5)) and found that my laborious conversion of vinyl albums has hit a snag. Using EZ Vinyl Converter (I have an ion USB turntable).

My imported songs no longer come into iTunes with the labels from EZ Vinyl Converter, but as EZACTmpFile (with assciated numbers after them, and then .wav). They used to come in with track number and track title shortly after it, using the import format from iTunes import preferences.

This greatly complicates my music importing task, which already involves a lot of work and time.

How can I get it to work again???
