Up until yesterday I was using HRD rotator quite successfully. I ran a serial cable from the rotator into a serial to USB connector because I didn't have a spare serial socket on the back of the computer. Now all of a sudden, it's not working, the computer isn't recognising the USB to serial cable. If I unplug it and then plug it back in again, it tells me that the software drivers have not been installed successfully. What is all this about? It's been working really great.

sorry Penn, my computer consultants are all out for a date...
i don't have any back up at home...LOL...
actually my two kids are the one helping me out with PC...
