Adobe Captivate 8 won't publish

Just got captivate 8, and very new to the whole captivate system.  Working on a PC at work and trying to put together some training videos.  Every time I try to publish the current project I'm working on Captivate shuts down.  I tried to publish as a video to my computer with no success, each time shutting down after the "generating video" went through 4 min and 55 sec of loading each time.  I also tried to publish it to youtube, and after waiting the 4 min and 55 seconds the adobe captivate video publisher appears and prompts me to login to youtube - except that it doesn't accept my user ID and password for youtube - each time generating this error message "Login failed. Specify the correct username and password, and try again."  This despite my login information being absolutely correct.  Is there something else I have to download to my computer to make publishing possible?  As it stands I can only watch my presentation on the computer I have the license for in the preview fields.
