Creative Prodikeys, midi flakiness, some days it works others not at all.

[Jenk2k]

I'm running one of those neato keyboards with the midi controller integrated into it and since installing PTLE 7.4 on my new i7 rig, i notice that some days i power up and click record arm on the midi track (to control BFD or Mtron or something) and MIDI Just won't light up no matter what I do. I check all the obvious stuff like midi thru and that drivers are all installed and stuff and some day sit works and some it doesn't.

Any ideas?
