I updated my OS this morning and tried to open a previous version of Pages Data Merge (PDM) that I used for a job last year. When I clicked to open PDM, a pop-up window indicated the following: "'Pages Data Merge.app' can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information."
In response, I visited your website and downloaded the most recent version of PDM. When I attempted to open it, however, I received the same pop-up window and message.
