Once this was done I plugged the cable back in and it came up HL340 in the device manager instead of USB2.0-Ser! The found new hardware wizard still came up, the drivers finished loading automatically and it was good to go. It's just weird because using the exact same cable I never had to do that before.

I downloaded your file to my desktop, it appeared as a type of blank read file, no exe. I installed Winzip as I use Winrar, just in case that was the problem but still same.

How do I open the file? I am running Vista 64 and cannot use the usb-serial adapter as mentioned in previous comments. I purchased it from Amazon, they sent me a disc with the driver on, but it doesn`t work, I think it`s because I`m using Vista 64. Many thanks for your patience. Thanks Kimsland I downloaded it again, played around a bit (as you do) and finally got it.
