Reply to Pitchfaders stopped working after NI update for TP2

I just updated my TP2 (to 2.1.1) via "Service Center" and both pitchfaders stopped working/ working correctly. Sometimes they just don't react (TP do receive the midi signal) and sometimes they react but doesn't slide more than 15-20% of their normal range - I have no idea what makes the difference.

I've tried the latest .tsi from DJTT aswell as some older ones but it makes no difference.
Any ideas ?

Thanks in advance
