No humans in the loop -- I've bought lots of software on-line, and the process is usually quite seamless. I'm not sure if I was dealing with GeoVid or Plimus; I think Plimus handles the on-line sales. This had to be the more paranoid transaction for a $29 app I've ever encountered. "E-mail for serial number must match e-mail address with PayPal." "Please submit phone number for verification." Then when my cell phone didn't ring -- it was right with me the whole time -- I checked the voice message which stated that "efforts to reach me failed, please go to URL address to verify that you did order this item," etc. Then the confirming e-mail told me I had to wait 48 hours while my order was being reviewed.

It's a $29 app!

Then I had to go digging for the serial number -- which the Web site finally surrendered to me -- when I did not get any further e-mails after four days.

The final punch-line? The app kept hanging, "ProteMac Meter not responding."

Force quit.

Delete.
