Upgrading LANDesk Management Suite 9.0 from SP2 to SP3

Hi,
I am trying to update our main server method LANDesk Management Suite 9.0 from SP2 to SP3.
As I update the software, an error message popped-up. It says
The core name cannot be empty.

Behind the error meddage,it says it is updating configuration and the location is "D:PROGRAM FILESLanDeskMANAGEMENT SUITCreateClientConfiguration.exe /rebuild
The core name cannot be empty"
Can you help me with this situation?
Any help is highly appreciated.
Thanks!
