Yes, I called the Support and Kent solved this one. I suggest you don't mess with Soloist Maker window like me hehehe! The solution is doing this on the Soloist Maker window:

"I can see what the problem is now. You have J_SWING.ST2 selected as the ST2 file for that soloist, and that's incorrect.

You can fix this by clicking on the "*.ST2" button, and manually selecting the correct ST2 file, REIGt211.ST2. You can find it in the BB folder. After doing this, you should be able to find it #1519 the RealTracks Picker again.
