Using Outlook Business Manager but SQL will not start

Question

When I start Outlook Business Manager it tells me that SQL is not running. I have followed all the procedures to try to restart it without success.
The SQL log is reporting the following
2014-01-22 09:38:43.54 Server      The SQL Server Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service. Error: 0x54b, state: 3. Failure to register an SPN may cause integrated
authentication to fall back to NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies.
2014-01-22 09:38:43.54 Server      SQL Server is now ready for client connections. This is an informational message; no user action is required.
2014-01-22 09:38:43.61 spid10s     Error: 9003, Severity: 20, State: 1.
2014-01-22 09:38:43.61 spid10s     The log scan number (36:96:1) passed to log scan in database 'model' is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error
occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup.
2014-01-22 09:38:43.61 spid10s     SQL Trace was stopped due to server shutdown. Trace ID = '1'. This is an informational message only; no user action is required.
Any help is appreciated
Thanks

Failure to register an SPN may cause integrated authentication to fall back to NTLM instead of Kerberos.
Helo Mark,
SPN registration failed, you can register it manually, see
Register a Service Principal Name for Kerberos Connections
Or you can use this tool:
Microsoft® Kerberos Configuration Manager for SQL Server®
