There are a couple of other suggestions that might help with your setup.
(You do have the date on your system set for today's date right? I have forgotten to change it on test systems sometimes).
You could go into Add/Remove Programs in your Control Panel, Select GUIDEPlus+ and choose the repair option. Once complete, re-open GUIDEPlus+ and download new listings.

Make sure you have entered the appropriate information for your location in North America.
