I’ve never had a problem renewing my license. Are you sure you have your correct FCC username and password? It is not the same as your Federal Regisration Number (FRN). If you don’t have one, check out https://apps.fcc.gov/coresWeb/publicHome.do
The FRN is the problem. There’s one already associated with the original license, but when we enter it, the system doesn’t like it. (This is the first time to renew.)
Thanks for your link; I’ll look at it.
