Re: md5 hash failed

If you are using the md5 hash verification, it is important that you are configuring the sdk correctly so that the MD5 hash in the SDK matches what you have specified in your Authorize.Net account settings.  If you have not set an MD5 hash in your account settings, then you need to make sure that it is not set in the SDK.
