I dont know ... but I spoke to CFBP and that is what they told me. When I called, the CS agent seemed to know what I was talking about after I gave her some information. She was able to use my WMT Store # and verify that the update went to that store. She rattled off billers that where part of this update that I knew dont work but didnt even ask about.
I am only going off what I was told, but it seemed legit when she was saying it. She also said it didnt affect KM or other stores and was just walmart. Maybe during this system update it affected all these places?
