Super Orders doubles tax

Hi everybody!

I'm using Zencart v1.3.8 and v1.3.9f upgraded from v1.3.9e.
I have just installed Super Orders module from this site:

http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=257

One for version 1.3.8(2.0 (Rev 48a)) and the other for 1.3.9

No other modules installed yet.

I'm getting the same error in both.

I have new order (attachment Clipboard04).
When I edit it for the first time(attachment Clipboard05) and click Cancel there are no changes and everytihing is fine.
When I click Submit it adds Tax again(attachment Clipboard06) and it doesn't matter if I change any of values or add new values.

When I edit order again all values(tax,total...) stays the same. It happens just when I edit it for the first time.

Can anybody tell what needs to be modify?
Thanks.

Still can't find the solution.
Please help.

DivaVocals:

The order editing features in Super Orders was never fully flushed out/developed. The upcoming Super Order release has deprecated all of the order editing functionality. We are recommending instead for Super Order users that they use the Edit Orders module for order editing functionality. The upcoming Super Orders release will also provide the necessary edited files needed for Edit Orders and Super Orders to work together..

In the meantime if you want to use Edit Orders and would like to use it with Super Orders, instructions for how to make these edits yourself have been posted in both the Edit Orders and Super Orders support threads. (the edits required are SUPER EASY to make yourself -- we are only including them in the new Super Orders release just to make it convenient for users) Search for "Edit Order, DivaVocals" and you will find my posts on this subject in both threads.

The Edit Orders support thread has the link where to get Edit Orders (the latest version is available on the authors website - the version in the downloads section is outdated)
