Since upgrading both of my computers (a MacBook Pro and a PowerBook) to 10.5 I've been getting a message asking me for a password for a computer that I had (and sync'd with .Mac) a long time ago. I've unregistered this computer from my .Mac account, cleared the sync information online, and tried other things, yet I continue to get this message. It won't take any passwords that I present it with, yet it seems not to be effecting a successful sync. It's just really obnoxious, and comes up frequently--I have my computer set to sync automatically.
Here's a screenshot, along with my old computer's name removed.
Does anyone know how I might rid myself of this problem?
Thanks.
