Thank you so much! That did the trick. :-) I actually did have the second button selected, but once I clicked "ok" on the error message it gave me the option in the security window to open the file anyway and it worked for every file.
I'm getting the following error message when trying to download the Logo Elements, Comic Elements and the PaperToons. I'm on a Mac using Sierra OS. How do I get past this? As of now I'm dead in the water after buying the Creator, PaperToons and Comic Elements.
