I was able to install Snow Leopard without any problems - but I can't do a Time Machine backup to my Time Capsule. The drive is not recognized and I get a "25299" error which refers to a problem with my keychain. I've gone into Keychain Utility and (several times) have deleted all the Time Capsule entries, but the problem keeps replicating itself. I was able to run backups earlier today and also reset the settings on the Time Capsule, so I'm sure it's not a problem with the drive. Any help would be very appreciated!!!!
