Ultra Mixer is Locking Up

I’m trying to work on my Ultra Mixer Software tonight, and for the last 1/2 hour, after I open it, and load tunes into each deck, I am unable to move anything with my cursor.

Does anyone have any clue or has this happend to anyone?

I also used the software for the first time last weekend. It only locked up on me once, for a 5 hour gig. not bad…but 1 too many times…It’s a good thing I had 2 cd’s as my backup.
