I really dont know. Make sure that if you used a proxy at some point, that it is turned off now. Also, you have probably tried this, but reloading mlb.tv or even rebooting your computer never hurts. It is odd that it happened to me, but that only happened when I was using a wierd proxy. If that stuff doesnt work, I would wait out on entering your credit card info until you can get an answer. Hopefully someone else at the cafe will have an answer.
