Eh... that's not a newbie mistake. Just the Cleverbridge auto pay thingie being weird. Seems to have nailed a couple of old timers too.
Since you missed out on a couple months due to the error maybe bring that up while you sort it out. Not sure what exclusive member content came out during that period so it might be worthwhile to you to figure out what WAS released that you'd miss out on by updating now.
Like do you want to simply renew starting today (and lose that few months of content) or back date the order/membership to get that exclusive content and pay the extra/lose a couple months off the end of your "year" membership.
If that makes any sense. I'm sure the Bakers would be accomodating considering the circumstances.
Cheers.
