Just upgraded from SEC4 to SEC5.0 Enterprise Management Service fails to start

I checked in Event Viewer to find this error;

Event ID 8004

General:

Initilization Failed.

Step: Migrating data if necessary

Error: std::runtime_error. Database upgrade failed. Please see KBA 113946

Data: ErrorUnexpected

I ran this in the command prompt;

C:\Program Files\Sophos\Enterprise Console>OSQL -E -S .\SOPHOS -Q "SELECT Name FROM SYSDATABASES" Name

 -------------------------------------------------------------------------------
        ------------------------------------------------- master

 tempdb

 model

 msdb

 SOPHOS4

 SOPHOS50

 SOPHOSPATCH


(7 rows affected)

Followed by this command;

C:\Program Files\Sophos\Enterprise Console>Upgradedb.exe -debug -sourceVersion=4
