idisk won't update!


I've got several Macs that have no problem keeping my .mac idisk current. My powerbook, though, won't update. It says "last sync failed" at the bottom of the window, and the Backup, Library and Software folders are replaced by text docs that say "The selected directory is only available when the iDisk is online. To access this directory you will need to take your computer online."

My computer IS online. running iSync doesn't help, it works normally but does nothing to my idisk.

what's wrong here?
