[HELP] Oxygen 49 sending random MIDI values

Hi guys. Basically the title says it all.
I've got my Oxygen 49 since May 2010 and around that time I noticed that the on board display sometimes would bug out and switch off. I looked up for this on the interwebz and I read that Oxygen bugs with MIDI Output from the pc, so I switched off all MIDI Outputs. 4 Months ago I was recording automation with the knobs on my Oxygen and after I recorded and everytime I use the knobs it just shoots random values. When I rotate the knobs it sends the correct values according to the postition of the knob, otherwise if I don't turn the knobs it just shoots random MIDI values.. Any suggestion?

PS: I tried resetting it, but it didn't solve nothing. Thanks in advance,
Kaspo
