I have recently updated my ServiceDesk MSP from 8315 to 9000

In help --> About - it shows Your Version 9.0 Build 9000, latest version, 8.3 build 8315

I have attempted to update to 9.0 build 9001, however it says I am unable to do this

Any help much appreciated - I can teamviewer someone on if it helps!

This is running on Windows Server 2012, with SQL Server.

Regards

Mark
