How do I fix a 'too many redirects' problem in network site dashboard?

I have gotten further in setting up a multipress environment since i did it all from scratch after joining wpmudev. Intent is to use market press/cubepoints/paypal to create a virtual online mall. Main site works fine. Multipress network site looks good using subfolder. When I try to go into network site dashboard, I get a 'too many redirects' error page. How do i fix this?
