We have had these issues as well, especially with the check box.  We have been extra diligent in double checking that box, but wonder if there is a bug that UNCHECKS it....

We have had a customer set up and have one transaction go through and processed, but then the next month, it doesn't and the box is unchecked.  How did it process the first month and then deactivate??? Has anyone else had this problem?

So incredibly frustrating since the only way to see if it is paid is to go through each sales receipt.. who has time for that.
