where and what is the error? - vb.net

Question

Site is running .NET 4.5, with VB. Uses SQLServer and ELMAH. I use VWD 2012.
Production site works fine, but local development site crashes with error:
"The specified string is not in the form required for an e-mail address."
when trying to load a page in the \Admin folder, which requires login.
The error comes up in VWD on a "Source Not Available" tab as soon as the login screen shows in the browser.
The error details are:
*System.FormatException was unhandled
HResult=-2146233033
Message=The specified string is not in the form required for an e-mail address.
Source=System

</error>
I cannot determine if the error is in the ELMAH process or in the underlying code somewhere. I have checked the email info in web.config related to ELMAH and all email addresses are properly formatted.
Everything had been working fine on the development machine until sometime in December, when all of a sudden this came up.
