Expired keys

I have (or had) a number of premium keys which expired at the beginning of April, after I had to change my CC, so autorenew did not work. I didn’t realise this until today.

Because I have no access now to premium support, am falling back to asking here if there is a way that I can renew these, or do I have to purchase new keys. I cannot find a way on the site. I have updated my billing information and reset the keys to autorenew.
