I've tried that but still no go. I am not sure what I did before, but it was working on this very same computer. I just replaced the hard drive, fortunately I had a copy of the software because as you know URC are being dicks about giving you the software you already paid for. My main computer is a new windows 8.1 desktop so I am only using the xp machine solely for programming the remote so I have got to get this thing going, it's pissing me off so bad you have no idea. My only other recourse is to try to get the editor software to run on windows 7 or 8 It's almost impossible to get the MX-3000 editor to run on the newer windows without a update to the software which is why I want to get it going on the xp machine.
