SlickTicket - Setup

I was able to run the setup to create the databases successfully but when I click on "permissions"  or "settings" pages, I get the following error. Thank you so much

Exception Details: System.InvalidOperationException: Sequence contains no elements

Source Error:

Line 49:     public static user Get(dbDataContext db, string name)
Line 50:     {
Line 51:         return db.users.First(u => u.userName.Equals(name));
Line 52:     }
Line 53:

The system works great. I found my fault in IIS.  Windows authentication was disabled and anonymous access was enabled. so I disabled anonymous access and enabled windows authentication and that error message has gone.
