Where are my folders?

I had a few servers setup in RDM and they were organized into folders. This morning when I opened it back up the servers are there but no folders. All the servers are just there in a list with no folders. If I edit the individual sessions they show the folders to which they belong.

I started connected to a blank .MDB and tried to add a new session in a folder and still the folder doesn't show.

Is there some option I'm missing to display (or not) the folders?

Thanks,
Bill
