M-Audio Oxygen 8 Midi install

[goldensection7]

Hello everyone,
I recently successfully installed my old Oxygen Midi controller for use with Ableton and everything was working fine. Yesterday, when I started Ableton, something went wrong or a setting changed and I can't get it to work anymore.

So far I have rebooted my computer and reinstalled the drivers for Oxygen. (I'm running Vista Sp2 64-bit & using a m-audio fastrack pro) & that didn't help. Back in Ableton, when I hit a note on the Midi controller, the small yellow box in the upper right of the Ableton interface flashes, so I at least know that it sees it. So I'm guessing that there's something wrong with my midi/ sync settings under preferences.

Under midi sync:
Control Surface: Oxygen8
Input: Legacy Keyboard midi in (I also have the option of 3-Legacy Keyboard Midi In)
Output: Legacy Keyboard Midi out

Under midi ports:
I have all the Track and Remote buttons switched on, which include "3-Legacy Midi Keyboard in & out", "Oxygen 8 input and output", and "Microsoft GS Wavetable Synth"

...and now Ableton isn't even seeing the midi controller and I have no idea what I did this time to upset the Ableton gods. I especially feel dumb right now because I don't use forums that often and I can't figure out how to upload my screencaptures. I'm guessing I have to upload it to it's own url or something. Please help, I'm baffled

The same thing is happening to me!
I've installed the drivers for my Oxygen8 midi keyboard (I'm on a Mac OS X 10.6.7). It installed fine and is recognised by Ableton. But when I hit a note on the keyboard, the small yellow box (in the upper right of the Ableton interface) flashes for about 5 seconds and then nothing happens.
I'm equally baffled. Am I missing something?
