Adobe Captivate video demo - zoom problem

I have used Adobe Captivate to take video demos of our company software for training successfully for a few years now. I have used it on both my laptop and the computer connected to out kit. Since I installed the 2017 version, I am no longer able to take video demos of my entire screen. I select "screen area" and "full screen" like I usually do and record. When I play the video back however, the screen has "zoomed in" and cut off the right had third of my screen out of the video! Today at work we had a demo of some new software in for one day only for a very important project and it was my job to get Captivate footage of the software so I can create a promotional video. All the footage I got is completely unusable because its cut off at the bottom and right hand side. I've tried changing every setting I can think of, including customising the size of the screen area and selecting the application to record instead but it does the same thing no matter what I do.

I;m at my wits end now and I've missed the one-time opportunity to get footage of our new software. How do I fix this so that I don't mess up an opportunity like this again? I never had this problem before it forced me to update to the 2017 version!!!
