DPM DotNet API Validation returning false

I am integrating with Authorize.net using the DPM mechanism, basing my code on the url below.

http://developer.authorize.net/guides/DPM/dotnet.html

Everything worked fine while testing, however, when I turned off test mode, my calls to AuthorizeNet.SIMResponse.Validate(MerchantHashCode, ApiLoginID) are returning false. I set up a MD5 hash code in the merchant account, and am using that same code in the Validate call so why is it returning false when not in test mode?

Re: DPM DotNet API Validation returning false

By looking at the source code. "isTest" variable on the "BeginSIMForm" method switch between the sandbox test server url to the production server url.
