WPMU DEV Dashboard doesn't install plugins

I have followed many support threads about 755 Permission and host server issues but.. This Dashboard Install is on my Localhost and the WPMU DEV Dashboard works just fine on an install on parallel folder. This issue is something else since I'm only able to use the Dashboard only on my first localhost install and none of the other installs work. My membership is gold so I should be able to get more than just 1 install?
