downloading

Just got an Uniden BC125AT and would like to learn how yo download frequencies to my scanner. What pc software do I use, and where do I get it? I'm finding that this is not an easy task for beginners, and I don't want to enter each one individually.

I have tried on to download the software for programming onto my scannner and have been unsuccessful. Any suggestions? I am trying to get local (Lambton County, Ontario) frequencies downloaded by computer onto my scanner.
