The short answer is no (I am not sure if you are the same person who emailed us about this, your post is about the same date, and we responded by email at that time)
I will post the email answer here.
Unfortunately Amazon have introduced some major changes to their associate program and APIs beginning August 15th 2009. The most important of these changes are that all API calls need to be signed, or they will be ignored. As a result of this, the Piranha Feed script will stop working on that date. I am not 100% certain, but I think what will happen is that Piranha Feed will simply stop displaying any Amazon products at all (as if no product matches are ever found).
Because of these changes, we feel that it is not practical for us to update Piranha Feed to work in the new Amazon environment. I am sorry that is the case. I am sure this is no consolation, but for the record, I should remind you that the original Piranha Feed sales information did say that we only included updates for 90 days from the date of purchase, and although we only used documented Amazon APIs we could not make any guarantees about future changes to Amazon APIs or the Amazon associate program.
However, going forward, I'm sorry, but you will need to find an alternate solution for your Amazon associate links. My suggestions are:
1. You can consider using the linking tools within Amazon.com's associate area. They have recently introduced a large number of additional linking tools and widgets - so you may find you no longer need a script as much as you once did.
2. If you look in the forums in the associate's area of Amazon, you may find recommendations or suggestions for scripts that you can use.
3. There is a script called "Associate Engine" (I have not used this script, and our company has no connection to its authors) which may serve your needs.
Information about the Associate Engine script can be found at -http://www.c3scripts.com/amazon/index.html
A thread in their discussion forum entitled "Does Associate Engine use AWS Access Key" includes a post from the author of the script, saying that they intend to handle the 15 August Amazon update -http://forum.abestweb.com/forumdisplay.php?f=105
(if you have any questions about Associate Engine, I suggest you contact its authors directly)
Please let me know if you have any questions, or if there is anything that I might be able to do to help.
