@WayneSchulz, this sounds like they are updating the product key automatically every 28 days. If they are, indeed, blocking credit card processing somehow with the product key, then this could be a problem in future. However, in my experience the product key does not affect whether APS credit card processing works. As long as A/R is installed and activated, the APS addition works. I am always careful to hedge my answer because one never knows what changes have been made in the latest product updates. This is of great concern to me, so I will carve out some time to investigate next week when I'm back at my desk.
