I'm trying to renew my membership and have had troubles with the online process... and yes I will give them a call tomorrow, but I wondered if anyone else has had a similar problem. Basically I can get through the check-out, but when I enter the CC information, it says that the number is invalid. This is the same CC I use for everything and that is not the problem. I recall in another thread someone mentioning problems entering their CC information. Anyone have any ideas?
