cntrl r and macbook air 2013 issue

Dear Livid Instruments, I've met this problem 1 month ago after upgrade my Macbook Pro to Macbook Air early 2013(with Mountain Lion). I've bought cntrl r 6 monthes ago.
When I use cntrl r+xpc with faders+macbook air in studio with light ableton projects everything is ok.
When I use the same configuration on stage with 20gb ableton live project and external clock from time to time controller lost the clock and freezes (red square in ableton script freezing). Everything works ok after reconnecting controller, but as u understand this is not the best workaround if you play live for 1 or 2 thousand people and you have to reconnect controller much more that 5 times per hour!!! :)) So.... It looks that I need your help! Next gig is on 14 September and I need the stable device.

ps: it seems that the main problem between macbook air (m lion) and controller on hardware or firmware level, cause everithing is ok on my old macbook pro
