You have to click "Update Channels" first and then you will see it. Sorry I forgot that step. I wish I could get my screen grab to work, I've done it before but it won't work for me today.
You aren't importing the whole library into your scanner, you're just importing it into iScan. You can choose state, county, etc without loading the whole shebang onto your scanner.
And yes, it's confusing, until you get used to it. Once you've used it awhile, iScan isn't too bad to use. Not WIN500 easy, but not bad.
