ASIN field value disappearing

I have CCK installed with the Amazon ASIN CCK module installed (http://drupal.org/project/asin)

When I hit preview, everything displays correctly (IE, I get the book cover, book info, etc embedded into my node)

However, if I save it, it seems that the ISBN number is not being saved to the database because upon saving, the book info is not there anymore. When I go back in to edit, the ISBN field is now empty. This is being done from the first administrator account so it shouldn't be a permissions issue.

I am also getting no errors or anything. It just disappears. The ASIN CCK module, and the CCK core are both the latest versions, and I tried using the developmental snapshot and it too does not seem to work. Anyone out there able to help?
