Happy it worked out. Not sure what would have caused the problem originally, but they should be able to "white list" your IP so it's accepted by their systems.
I actually work in a similar industry in IT, so I'm sitting in a Hulu competitor's office as I type this, haha.
Anyway, the problem may come back again because most consumer internet providers give you a dynamic (changing) IP. So don't be surprised if you lose power (or just wait a while) and the issue returns.
