Just downloaded beta2. I'm running Windows 7. I created a site and when I browse to it I get the under construction message but when I go to admin I get

Server Error in '/' Application.

HTTP Error 400 - Bad Request.

Hello Dan,

Could you check whether you have some special chars in the url or duplicate slashes, dots and other not alpha numeric chars.

Best wishes,

the url it's going to is

localhost:42389/.../sitefinity

Hi Dan,

You have two slashes in the url after the port of the web server. This error appears when you have not added project name. Please delete this project from the Project Manager and then create a new project where you set the Project Name

Best wishes,

Doh!

Works great now.
