If you have trouble registering on line for NJ Code Camp II because of your “Live ID” there is a way around it. When you click on the Register link if you recieve an error message that there was trouble with your Live ID, simply choose to log on with a different e-mail account. When prompted, go ahead and use the same e-mail account again anyway and you should get through.
According to the message on the right side of the page Microsoft is aware of the problem and it is not specific to NJ Code Camp. It is a Live ID/Passport issue.
