I didn't receive a username or password because I bought the actual book before he had an E-book available. (It was a couple of years ago). Sorry - I wish I could be of more help.
On the website it says his e-mail address is: jimian@yahoo.com but I've never had to e-mail him before, so maybe he's just really busy?? Maybe you could try mailing him a letter, it will take a little longer, but at least you know he'll get it.
If you don't have his mailing address it is:
Jim Iannelli
7148 NW 100 Terrace
Ft. Lauderdale, FL
33321
There's also a # on the website (I'm assuming it's his phone #)
954-294-4184
Did you try looking at the FAQ's on the website - they might be able to help
