Looking at the log you’ll see error messages like this:
"0","Cortex","Error","Cortex//OpenMySql(0): Project database version is newer than this version of the software. Database Version: 0.9.4444.30, Software Version: 0.9.4444.23","","05-16-2014 13:42:43.122","7740","1","7366220279","CD-DA3"

“Project database version is newer than this version of the software” indicates that a newer version of Cortex had been run in this shared environment (in this case, v1.5).
Currently, on a shared database, we don’t really support having mixed versions of Cortex running. Keep this in mind as you are doing upgrades. For testing purposes we always recommend creating a test environment if you’ll be running on the same hardware.
If you need to roll back your shared database to support v1.4, let us know and we can help. Otherwise, I’d recommend continuing with local databases for 1.4 and testing the share with v1.5 until you are ready to roll it into production.
