I visited my parents -- a four-hour trip -- two months ago to set up this machine, but it didn't work. I'm now back at my parents' home with a second machine, and I'm having trouble setting it up. I went through the same fake "We didn't find a phone connection" message (even though the phone connected to the machine had a dial tone both before and after this printed message). When it printed the security code, I went to the nearest coffee shop with Internet access, but presto's site won't let me enter it. I get this messge:

XXXXX's Printing Mailbox has not called Presto yet.
See below for details.

If XXXXX's Printing Mailbox is already setup and has printed a security code click here to enter it now.

I have pressed "click here" several times in two browsers, refreshing the page several times. Nothing. What do I do now?

I've worked extensively in technology for many years, and I can't make it work. If I can't, how can my elderly parents -- part of this machine's elderly, technology-averse target market -- make it work? If this thing gives my elderly parents the least trouble after I leave, they'll pitch it.
