Samsung Galaxy S

When scanning test-pdf I will get error message:
Whoops!
Try scanning the Popcode again.
403 Forbidden

My phone is Samsung Galaxy S, Android 2.2
What is the problem?

... IT WORKS! "Try scanning the Popcode again." and again... was the solution.

It sometimes mis-recognises

It sometimes mis-recognises the Popcode unfortunately. Don't worry about getting the overlay to match exactly, a focussed image where the Popcode is a reasonable size will work best.
