Memory recall issue when importing library and saving histories.

I posted a while back, after my drive was erased, and I was having trouble importing my library from the USB drive I use to play.  Essentially, the playlists would all import properly, but only 20% of the library contained all the correct data, with grid info, cue points, notes ect.  With some suggestions from Pulse, I've tried several different methods of importing and re-importing, but no luck so far. 

The reason I am creating a new post today, is because I noticed another issue that I'm hoping will help resolve the bigger problem.  It seems that after I play a set, plug the USB into my laptop to access the playlist history, only about 20% of the songs saved into my set history, have all the cue points ect.  The rest of them are blank, as though I'd never adjusted the grid, set cue points ect.  What's strange about this, is that the songs on the USB do have all of this information on them.  But when Rekordbox forms a history from my performance, it seems to have the same bug that is not allowing me to successfully import the library from my USB onto my laptop.  What's also strange is, that when the USB is plugged into the CDJ, the History section is empty.  The histories appear when plugged into rekorbox on my laptop, but I'm not able to access them on a CDJ.  Never had this problem in the past.

So, Pulse, any new ideas on what might be causing these issues? I really want to get my library imported from the USB correctly so that I can start using SYNC again.  As it stands now, I am only editing playlists on the USB itself.

Thanks in advance!
