wpmu dev plugins are not working

I installed the wpmu dashboard plugin. Each time I attempt to enter my account information when I click the login button I get re-directed to the wp-login page. I tried re-installing the plugin but no luck. What I need to use is snapshot. So I downloaded that plugin alone and installed it. Now when I click on any action in the snapshot plugin it does the same thing, kicks me out to the wp-login page. How do I fix this and get your plugins to work?

I tried adjusting some settings in some of the other plugins (non wpmu plugins) to see if all my plugins were broken but they are working.
