Just noticed that Help in TotalMix FX (Version 0.989) doesn't work. I have a RME Fireface UFX (DSP-SW Version 1.51, Driver Version 1.029, Hardware Revision: 352) connected through USB to a computer using Windows 8 Pro x64.

Let me add a Google German translation:

Let's hope that in a few months I'll get an answer from RME.
