Connection to SQL Database

Hi All,

I am running Backup Exec 2014; Version 14.1 Rev. 1786 (Latest)
On Windows Server 2012 R2

Recently Backup Exec 2014 just finished it's trial time.
I was previously able to connect to and backup SQL.
I had already installed all of the required licenses on the server prior to this time.

After the period ended, I am able to receive a connection from within Backup Exec to any of the SQL servers, but cannot open or backup the database in the selection list (I receive an incorrect logon error) The Backup error was not helpful either.
I am able to connect to and backup Sharepoint and Exchange which are connected to the same license, Applications and Databases.

Any help much appreciated,
Steve
