Recording issues with DJMT-1 and traktor 2.6

I seem to have an issue recording since the update to 2.6. it seems to be a setting issue on internal or external mixer mode internal mixer works fine but all i get is a high pitch whine when listening back to to recording. On external mode i get a decent recording but have no control over the mixer.

This is annoying as it worked fine before this update i have all the latest firmware installed... please can someone help really frustrating not being able to listen back to mixes!
