icprncss, if you are still seing a problem that has been sorted out now for some time, then the problem has to be somewhere on your own computer, imo.
in “clear recent history” on your Browser, clear as much as you can. With forefox I have options to clear browsing and download history, form and search history, cookies, cache, active logins and offline website data. Clearing all or as many of them as you can, whilst logged off from this site, should help. Cache is the most important.
If that still doesn’t clear it then try using a forced refresh.
You say you getting error messages on your serial numbers page, and also your subscriptions page, can you show us a screen shot of the error message.
As Frank said your PC membership is fully active.
