Done, running as admin, addresses the RT folder all right, selecting a RT, the generate bar works for 2 secs, and then stops. But the track plays.

Loading a MGU midi only works, slow generating, and it works ..

Loading a full blown RT loaded MGU file works but stucks at 90% again, for a long while. The track has not been generated yet message appears when pressing play. (Pressing DEMO produces sound).

The yellow popups indicate somethings generating still, over 5 minutes at least. And after about 8 minutes it works suddenly .... But all it takes tooooooooo long.

PS i am going off-line in a minute or so ... getting late.
