Cully, Have you upgraded the R2's to the newest version of code?. We ran into a lot of trouble with the R2's that was fixed with 06.05.02.
Also, if you would like to get in touch with me offline I have a number of tools that I created for working with the R2's that I would be glad to share with you.
