Hello everyone,

I am trying to install and use Umbraco for the first time but a strange error occures. I have looked up the documentation, searched through the forum but found nothing. The problem is:

• During the installation steps when I chose "Install Runaway", the first time I got an "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" error. After this error I go back and again while "Install Runaway" option is selected click next and this second time I got no error. But this time at the end I see that Runaway template is not installed.
• It should be doing good without a "sample site" if I could admin anything. When I start Umbraco everything is strange. For example when I try to add a new content Documents Types are missing, which I mean the "Choose Document Type" drop-down box is empty so I cannot create a new content. Or when I try to create a new document type from "Settings -> Document Types -> Create" again I got the same error Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"

By the way, I have installed Umbraco 4.0.3 and the latest Ultidev Cassini Web Server.

Any help will be appreciated.

Best regards.
