Hi- I recently upgraded to a new computer with Windows 8 installed. When re-installing my Toneport UX-2, I've found that now it merely acts as an audio interface--I can play my bass through it, and it routes audio from the computer to my amp/speaker setup [i couldn't use my previous audio interface, an EMU 4040, as the slots no longer match up with the new computer]. But i seem to have lost access to all but a handful of my [factory] amp/cabinent patches, and even the ones that boot up are ignoring anything I do with their "knobs". The only "page" that affects the output is the mixer page--the volume knobs will still raise or decrease the volume. All the amp heads' volume, gain, or EQ knobs do nothing to the output. HELP!
