DiskXtender 6.2 - what licenses do I need?

Hi,

I'm running DiskXtender 6.2 on a pair of clustered (A/A) Server 2003 boxes. Media is NAS disk.

License server shows:

DiskXtender File System Manager
File System Manager Licenses: 2 (2 in use)
Storage Capacity: 1 TB (386 GB in use)

It has now come the time to renew support on these licenses. The following is being shown on my update quote;

DISKXTENDER FOR WINDOWS 1TB CP
DISKXTENDER FOR WINDOWS FILE SYS MGR
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR CLUSTER
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR CLUSTER
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR CLUSTER
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR SERVER
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR SERVER
DISKXTENDER FOR WINDOWS FILE SYSTEM MGR SERVER

Now this is obviously wrong. However, I'm unsure what licenses I do need to renew for the set-up I am running.

Any info would be gratefully received.

Regards

Mark.
