It appears that during the recent update, we gotten the order link within the app mixed up. This let to the order link being launched to the CM Batch MMedia Date Changer order page instead of the CM Batch Photo Processor page. The fix will be implemented in the next update.
For the time being, either use the CM Batch Photo Processor description page, the Help File or the following link https://sites.fastspring.com/batchimage/instant/cmbatchphotoprocessor to purchase the app.
We are sorry for the slip up.
