How do I create a new archive database for the K2Log?

Hi

I have a huge K2 log database on my SQL server that I would like to reduce in size. I've tried to use the Archiving application tool but when I export from the K2Log I get an error message:

"The Following error occured with the export process: The Archive Database contains archives from another K2 Log Database."

The "Archive Components" PDF states that this means I need to create a new archive database but does not explain how to do it.

Any help much appreciated.

best regards
