Object reference not set to an instance of an object

[AnthonyV121]

I have an issue with a specific Windows 2003 server. My code is working
on 15 other servers of various configurations(10 of the 15 are Windows
2003 servers). I receive an "Object reference not set to an instance of
an object." error. I cannot figure out why. I have tried compiling the
code and receive the same error. The error is on line 20 of
iSecure_Authenticate.aspx.cs which is the last line of code in this
post "iSecureMembershipProvider iSecure = new
iSecureMembershipProvider();".

This is the code for my class
filename: iSecureMembershipProvider.cs (located inside App_Code
directory)
