Rekordbox loads and begins analyzing tracks.

When I select a few tracks (10-15) and I click "Analyze track", sometimes rekordbox does it without problems (meybe 10% cases), but in 90% cases after few tracks aplication crashed with "Unexpected application error". After run rekordbox again, shows information about error in database collection, and restores backup from previous close rekordbox.

It's very irritating, the same problem is sometimes when I analizing any single new track when I play in performance mode.

I use Toshiba Satelite P850, 16GB RAM, IntelCore i7.
