I had the same problem. Went back and triple-checked that I had added the correct hidden fields to the correct templates as described in the text file. I had done everything correctly.

However, I had used some really long hidden field names using a mixture of upper-case letters, lower-case letters, and numbers. On a hunch I changed the hidden field names to some 8-to-10 character all lower-case letters and it started working.
