Unable to install wpmu dashboard on brand new multisite

Hey guys,

ive just set up a brand new wordpress and converted it to multisite,

im up to the point where i want to install wpmu dashboard but, wordpress is able to install it, but as soon as i click on network activate, the site becomes totally unresponsive, just a blank white page for anything i try to load.

i have set up a username and password for you guys, i will pass the details on in a more secure place.
