Saving and playing Animate project

Hey there. So I used Animate to create a simple drag and drop-style game without any issues, but I am having trouble exporting the project. When I open the game as an .SWF file, I get a small white box with a 'movie not loaded' message. Also, I get "Safari cannot open page" when I drag th icon to my browser. 

I have tried exporting the game as all available file formats but none have worked. Should the game be saved as an .SWF file and if so, am I having an issue with the file and not Animate?

Also, I am on a Mac.

Any help is greatly appreciated!
