I can't seem to sign up as a paying subscription customer. The "upgrade" button always says "Whoops... try again later"

Hello Jim,

Thank you for your question about paying. I was able to verify this. Yesterday, we moved our database to a new provider, and somehow missed this.

I gave you a free month for saying thank you for alerting us to the issue.

I hope you don't mind the temporary workaround. Please let me know if I can help further.
