I have a similar problem and it only just started to happen. Tracks are missing in midi only files. Tracks are also missing in RealTracks when an instrument is frozen. Even worse, the program now freezes about 6 bars into some tunes and then crashes! I have not worked out the common factors here but the crash seems mainly to be with old midi files of which I have hundreds with no suitable RealTracks to replace them.

I am running Windows 7 64bit and have installed all the latest updates.

Actually, I think this problem only started after I installed build 329.
