Hey, Seems a lot of people have trouble with this. There are a few things you can try: 1) Try to reinstall the 10.2.6 update over the original 10.2.6. If there are any corrupted files this should fix that. 2) If not insert the 10.2.5 CD or what ever previous Mac OSX CD you have. It doesn't matter what version because you can always download the 10.2.5 updater later. Then install the previous version over 10.2.6. Try this and tell me if it works. CJ
