Wierd SampleTank 2.1 stuff

[Scoops]

Has anybody worked with the new ST 2.1 engine yet.
I find that it doesnt work in racks, and cant playback imported midi files. It seems the only thing I can make it work with are freshly created midi files in a brand new edit. As soon as I bring in a ST 2.0 engine, I loose audio. Now IK Multimedia has issued the following statement

IMPORTANT: due to the enhanced features implemented, SampleTank 2.1 is NOT session-compatible with SampleTank 2.0. This means that you should NOT uninstall SampleTank 2.0 if you will need to work on previously made sessions using SampleTank 2.0.

Is this wierd or not?
