Ive noticed this also. Cant the program owners at least leave up the original backend for a limited time period so we can make sure rebills are being carried over. For the price of nats it should be able to carry over previous stats, but since every paysite backend is different its probally to much work for the nats team
. I can understand the use of nats for program owners, its a hell of a lot easier to keep track of affiliates, chargebacks and fraud.
