Time machine kernel panic

Question

I have a 2011 MBP 13. Running 10.7.5. My Time Capsule quit working awhile ago, so last week I reformatted it and did an ethernet connection backup from my and my spouse's MBP (also 2011 13 inch, 10.7.5). Worked great for about 5 days. Today I went out for lunch, came back and my MBP had crashed. I rebooted and found it had a kernel panic. I sent in report to apple. Now my Time Machine won't back my computer up, I get "The backup disk image “/Volumes/Data/Camille’s MacBook Pro (2).sparsebundle” could not be accessed (error -1)." I have rebooted both my MBP and the Time Capsule, no luck. I have the 1TB time Capsule from 2012. All latest updates are current.

First, if this is your only backup, you must make another full backup to a locally-attached external hard drive. One backup is never enough to be safe, and backing up over a network is less reliable than backing up locally. Then try each of the following steps that you haven't already taken.
1. Restart the backup device. You can do that by disconnecting and reconnecting the power cord.
2. Hold down the option key and select Verify Backups from the TM menu in the menu bar (not the Dock icon.) This operation may take a long time. If the menu-bar icon (a clock that runs backwards) isn't showing, check Show Time Machine in menu bar in the preferences.
3. Erase the backup device. With a Time Capsule, you do that from within the AirPort Utility application; see its built-in help for details. All backups will be lost, so don't do this until you've backed up to another device. After erasing, select the TC again as a backup destination in the TM preference pane. The first backup should be made over a wired connection, if possible.
