I am having a similar issue. I have Idea how to resolve it.
Pod Farm 2 will not process audio as a VST plugin
It has always worked flawlessly. POD FARM 1 works great, the standalone version of both work fine.
I uninstalled all POD FARM 2 from my computer and reinstalled with Monkey, exact same issue. It's like it wont allow me to select an INPUT on the mixer view. I am using a UX8 with newest drivers. Please help!!!!! This is driving me nuts! I use this VST on all my guitar, bass and VOX, I also use it pretty heavily on my VST instruments. I have dozens of songs that need to be mixed down and mastered for my next album and I feel crippled.
I am using Cubase 5.1
