rmx 2 et traktor: crackles and mapping

ive got the new rmx 2 but unsuprisingly, teething problems: i hope fellow forum members can shed light and in turn, help each other..

i have is crackling noises when using traktor 1.2.7.  the problem worsens over time using the rmx 2, accelerated by using the fx. im using (10.5.8 2.4ghz core 2 duo) and updated the rmx 2 drivers (v4.47)

the problem does not appear to affect djuiced or vdj but i need to use traktors midi mapping capability.  i assume no ones created a midi map for it yet?

id upload my own mapping so far, but cant seem to map the pots/knobs (eq, volume etc.) yet: anyone else managed/know how to?
