None of links in header are working.

Hi,

I downloaded 30day trail version of Jaspersoft Enterprise edition (v 5.2). When i login as superuser, none of links present in header seem to work. I need to create dashboard but when i follow create->dashboard, it doesnt work. Am I missing something out here? Even when i click on any user, its properties doesnt show up.

Any help would be acknowledged since i have to submit a project by sunday.

Thanks.
