Publishing the swf file in Captivate 8: videos unable to load

This is my first time using Captivate. I am still using the free version of Captivate 8 from a Mac. I have created an online module for my college e-Learning course but, I can't get it to upload right anywhere! I am trying to upload the swf. file to Google Sites but the videos display a connection error message and never play. I have read everything I could online but nothing is working for me. I tried uploading a SCORM zip file to Coursesites and got an error message as well. I am not sure what I'm doing wrong...
