Adding sites to Trusted list in IE (all versions above 6)
The program crashes at
var subdomain = new Dictionary
The message that Visual Studio says is "Argument exception was unhandled"
I'm not sure how to fix it or what it means? Any help would be appreciated.

You have duplicate keys. Dictionary requires keys to be unique.
