What if I click on attend but the Centra Client does not launch?
A “login ID already in use” message indicates you are already attending the Event on another PC, using the same ID as another user, have another version of the client open, or clicked the Attend link more than once. When the “Preparing Centra” window appears, follow the directions in the window to install the client. If you see this window more than once, you may be attending an event on a different server. Or, if you have cookies disabled in your browser, enable them to not see this window every time you attend an Event.
