Evening all
I recently upgraded to El Capitan, but had a few problems so reverted to Yosemite. In this meant I lost my Shuttersnith Backup programme.
Tonight I downloaded a fresh copy from the App Store, but I get the following error message: (it appears twice)
"The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store."
Then I get a box with: "Failed to initialize the store"
I have rebooted my Mac, deleted and downloaded a fresh SS copy, still no worky....
Please can someone help me.
Thanks
Paul
