Okay. Just got off the phone with the PGC. The problem is that the company that used to handle online subscriptions decided to stop doing that but the webpages are still there with absolutely no warning that they don't work. But I was able to renew over the phone. Too bad the PGC can't afford to maintain their website. Hopefully my subscription renewal will help that situation. Just kidding!
Oh, and BTW, perhaps my useless rants will help someone else avoid the same problems in the future. That's one of the benefits of social media. Or so I thought....
