Thanks for the prompt response!
1) Per my understanding, verification occurs when PayPal sends a message to the email adr entered ... that email provides a response link which provides verification to PayPal. I was wondering how that can occur since the email entered is a false adr.
2) I do have the module set to a test mode. I was wondering exactly what steps I must take to do the verification. Step 1 do this, step 2 do something else, etc.
I have created the accounts in the PayPal sandbox. Do I need to enter my actual credit card number to verify it is working, or can I enter a bogus credit card number?
3) I deleted the bogus product / shipping options / instant download. However, I am getting the following message at the top of my page, "Warning: The downloadable products directory does not exist: /hsphere/local/home/eisenbei/mikeandclyde.com/catalogdownload/. Downloadable products will not work until this directory is valid." How do I get it to understand I am not selling a downloadable product?
