Hello, Has anyone else had issues with entering their serial number when attempting to start using iwork? I knew about the issues with the first release so I downloaded the updates immediately after installing the program. Now, I try to open it for the first time and I get the screen to enter my serial number; I enter it but the "continue" button doesn't highlight. Apple online support addressed the issue but their solution did not work for me. Do I need to reinstall the program? Would this be a problem since it would be installing the first version over the updated one? HELP!!
