I don't think that the FaH website will know about your team number change until you complete a work unit under that team number.

As I understand it, when you configure your profile, it's just stored locally on your machine (in fact, if you run multiple instances of the FaH console, each one has its own configuration which could have different team numbers), and then sent up to the FaH site when the work unit is completed and results are sent.

Have you completed a WU since changing/setting your team number?
