New to OpenGribs and gribs in general - just learning. Prior to downloading a file for a specific area, one must be connected to the Internet. My computer is connected but the "download - GRIB" window has the "Download" button greyed out. I click on "Connection" button and have a choice of "Direct connection to Internet" or "Connection with a proxy". As I am at home, I clicked on "Direct" but it makes no difference. Any ideas how to connect and download files? Thank you.
