Just bought a 12/2000/80 and have a sinking feeling I made a big mistake- looks like this is the only tech support they offer. Can not find the inverter thru the MK 3 and yes the proper drivers are installed, inverted is turned on and it is not the computer, I have tried several. Seems there was a question just like this 7 days ago and no answer. Where does one go if the community can not answer the question?
