Clean install on my Windows 7 media PC. J River installation went fine. Configured the TV tuner, which identified all local channels no problem. However, when I try to populate the program guide, the MC2XML command prompt window and configuration screen v1.4 appear, asking for the service, options and zip code. I leave it as default and click OK. After that, nothing happens. The Please Wait, loading window remains, the command window never changes showing the config info, and after about 90 seconds the config window opens again. Just goes around in a circle. It seems the setup never completes.
Running as a local user with admin rights, so there shouldn't be any permissions issue.
