gn888 - Thanks for bringing this to our attention. I will follow up with you via email.
The Adobe ID which you used to post to this forum also has a subscripiton to FormsCentral Basic, Monthly, which renews every month.
This is likely simply a case of a typographical error in the email, as it incorrectly states that you have been renewed for another "year" instead of another "month".
However, we will investigate this. Thanks again.
