'ello 'ello...

So I FINALLY got around to trying the update. I have a standard looking serial cable but I had no way of really knowing if it was a null modem cable or not, but I decided to give it a whirl. I followed all the instructions in the installer and the error I'm consistently getting is "Cannot connect to receiver (rx/tx)". I tried both serial ports on the computer I was trying, in combinations of COM1 and COM2 for each. Nothing worked, same error every time. One other possible issue is that I was using a computer that I do not have admin rights on, so if the installer was trying to alter the PC's registry, maybe that was a problem too?

Is this a pretty good indicator that I'm using the wrong cable? I'm asking around the network department here at work to see if they'll loan me a verified serial cable to try again this weekend, but I figured I'd post my question today and see what you guys think.

Thanks in advance!
