Just invested in a TC as my MBP had to go in for repair. Got it all set up and backed up, and was working great. However, having got the MBP back with new logic board, its stopped working. Backups just fail, and if I open Time Machine, it doesn't see the back ups made before the MBP went for repair. The Time Capsule shows up in the finder OK, as being connected, and with the .sparsebundle file visible. It also shows up in Airtport Utility OK. Any pointers to get this going again much appreciated!
