I continue to have this problem and have not violated any of their rules, as has been suggested here. Two e-mails to MyPoints came back with the repsonse that they were looking into the problem and would get back to me. Never heard a thing. Refreshing your member key corrects the problem, but you have to do this everytime you go to the site or you won't accumulate points. MyPoints has been a big disappointment with terrible service, as far as I'm concerned.
