"No suitable files found"

No matter where I pick, albeit I've not tried the entire globe, I get this:

It says "No suitable file found."

If I click the link (in this case it's http://forecast.weather.gov/product.php?site=NWS&product=FTM&format=TXT&issuedby=GYX) the link says "None issued by this office recently."

I expected similar results to those seen on the aweather site - for radar files to actually load.

What happened is nothing of loads. Zooming in goes to a map with no overlay of radar or anything else.

Just in case, I'll attach the image.
