RESOLVED
This issue with purchasers receiving an “error occurred while creating your order” message should now be resolved. Please let us know if you continue to have any issues.

Update:
While I have not heard back from Google, it does appear as though purchases are going through again. I still have an open ticket requesting and update and more information on the issue. Thank you for your patience.

There is currently an issue with purchasing our app from the Android Market. We have a ticket open with Google. We apologize for any inconvenience. We will update this post when the issue has been resolved.

Thank you.
