Greetings

I'm sorry for posting this, I personally hate threads asking for help from a noob. But this is the only place I could think off when a friend of I asked me for help.

I never coded asp.net before, but am an advanced vb.net dev.

He sent me a project:
http://www.mediafire.com/?vhh3ee4dprh9md8

He asked if I could fix the error:

Code

Unable to cast object of type 'System.Security.Principal.WindowsIdentity' to type 'System.Web.Security.FormsIdentity'.

This is a full image of the error page:


I'm also currently reading asp.net tutorials hopefully to fix the error.

Please let me know If you can help.

Thanks.
