Reply to Kontrol X1's froze during gig!!!! NOT COOL!!

This weekend i was playing out and my X1's froze in the 3rd hour of my set!! PEAK TIME!! Luckily the TA10 interface and Traktor 2.6 were still working fine, so i used the laptop keyboard to play/cue and my Xone 92 for mixing. I then did a Reverb washout and put on a set on my ipod. Then restarted the laptop, didn't help. I then re-installed the X1 drivers, deleted my controller tsi and re-imported my TSI and then things worked fine.

I am on Snow Leopard 10.6.8, the last version of Traktor which supports Snow Leopard and all the latest drivers for the X1. This had happened once maybe 3 years ago and things had been fine since then.

I cannot afford the same glitch on NYE.
Any idea why this happened and what i can do to prevent this from happening again ?

Reminded of that Deadmau5 video in which he started banging his X1 on the table!!!!

Thanks!
