Cannot insert the value NULL into column "ServerName' (49150)

When  running the Backup Analyzer on any database,  the following error is displayed:

Cannot insert the value NULL into column "ServerName', table 'LiteSpeedLocal.dbo.LiteSpeedDatabase'; column does not allow nulls.   INSERT fails.  

Cannot insert the value NULL into column "ServerName', table 'LiteSpeedLocal.dbo.LiteSpeedAnalyserTests'; column does not allow nulls. INSERT fails.  

Backup analyzer fails if value returned from SELECT @@SERVERNAME does not match machine name

Steps to Reproduce:
1.   install sql server with a default instance, install 5.0.0.10668
2.   after installing sql server, rename your computer (reboot)
3.   open the LiteSpeed UI, select a database and choose backup analyzer
4.   run a new test and it will fail with the error above.

1. Open a query analyzer and confirm the existing server name value;

SELECT SERVERPROPERTY('SERVERNAME') or SELECT @@SERVERNAME

2.  Run the command below to add the correct server name.

Use Master
go
Sp_Addserver 'your instance name', 'local'
GO
