Actually id did start fresh with a new engine library, new Serato library , and importing the crates directly into engine using the Serato tab on the left side.
I get all the info with the exception of the hot cues.
If I use a rekordbox pen drive that was preciously used on my sc6000, I get all the cue points from RB, but I have to first work my playlist on rb, then export to a drive, and then import from a drive to engine.
Its a workaround that works but I want to avoid.
lets see if the engine support team finds out the issue.
