Akoustik Piano won't "always" work

I have Komplete 5 and all the other instruments work just fine. With Akoustik Piano, I can load the instrument and play it, but once I try to record the meters peak out and anything I play on my MIDI controller continues to peak. I don't know how this is possible since it's MIDI, I've tried updating Akoustik Piano from the NI website and I still have the same problem. Has anyone else encountered this or know of a solution. Thanks! -TreyThree

Didn't the workaround in your other thread work?

This happens to me when Akoustik Piano is the only thing in the entire session. I will look into the Kontakt 3.5 Beta, thanks Geoff!

Same here - but only on Vista 32. Tried it in XP SP2 and it works fine.
