Afther a succelfull installation of SugarCRM 4.5f on a MSSQL 2005 db server, i want to descibe how the system can be restored if a situation occurs.

I have made some customiztions to the UI and everything works just fine.

To back up the complete systems i did the following:
Copy the whole CRM directory to another location.
Copy the database to another database (on the same server)
I altered the config.php file to meet the new database settings.
I restarted the webserver.

The backup seems succesfull because i can log on to sugar an list all my existing accounts and contacts.
But when i want te view the details of an account or contact i get the error:
SQL Error: Statement terminated.

I realy dont understand what goes wrong here, the confusion comes from the fact that i can log on to crm, list my data but not be able to view or create new new data entry's

Can someone point me in a direction where i can dind a solution?
