MyAssistant - attached Crystal Report fails to deliver

SUGGESTED

I am setting up MyAssistant with a new Send a Report task.

I can attach a PDF, Text, or other document to the Email portion and the email sends successfully.

However, when I attach a simple two-parameter Crystal Report and manually run the task, an email is never received.

Also MyAssistant does not produce an error message. 

How can I troubleshoot this failure?
