Need flash developer to edit xml driven flash template

I have a template which name is Activeden Extendable Flash Template.


There is a "gallery" section in template. It uses XML for images. I have .fla files but I cant open it. I think it uses Flex Sdk.
I need to add one more category list.


Example:
Category A - Category B - Category C


Detail View of Category A
Part 1 - Part 2 - Part 3


Part 1
Image thumbnails


In original:
Example:
Category A - Category B - Category C


Category A
Image thumbnails

Mostly Xml Driven flash templates have XML document where you can edit most of the things i can give it a try my skype is floralchamp

Can anyone help?
