Cross RC 1.5.0 Problems + Fix

Hi guys,
i recently had problems with RC1.5.
1: No matter what buffer-size i choose, i had digital crackles on top of the running track.
2: When scratching Deck A the Timecode qualitiy of Deck B would also go down, and the track would sound like !(&/$§.
So i tried de- and reinstalling it, but it wouldnt help.
In my despereation i also erased the preferences folder and reinstalled it again -> no more problems, but my collection is erased as well. (guess i erased too much
So i´m letting you know that now it works fine again plus i can get down to 0,3ms latency when i turn the key-lock off^^
Maybe you guys can figure out what the problem was.
Lovin Cross!
