Hi, deadspot80, it's Deb from the Amazon forum. As we discussed there, at this point, unless you can get a U.S. credit card tied to a U.S. address you should start looking into another way to purchase books (since the gift card downloads are not working).
Purchasing books from sources such as
Fictionwise.com and
eReader.com, may require some conversion to work on your Kindle.
Here are some threads to become familiar with:
Amazon Kindle Hack - python script tools to set up your Kindle for reading DRM content from other sources - you just need the links from the first post
How to Make Igorks Scripts Work - how to use the python script tools you got from the first link - I found post #4 to be the easiest to understand
The Idiot's Guide to running Igorsk's Python Scripts - more on how to use the scripts
MobiPocket Decoder Tool - more tools
You should also become familiar with the following free software:
MobiPocket Desktop Reader - Windows only
http://www.mobipocket.com/en/Downloa...ilsCreator.asp - Windows only, install the Publisher Edition when given the choice during installation
Stanza - Window and Mac
ConvertLit
MobiPearl
How's that for a start!
