Captivate Reviewer Quiz Issues

Hello!

I am using Captivate 8. I was making a responsive project, but ended up scratching it in favor of a non-responsive project. I cheated and copied/pasted the slides out of the responsive file into the non-responsive - which seemed to work fine. I was able to preview the file in Captivate and in the browser without any trouble. My coworker could not get anything on the quiz slides to work - in the Captivate preview or in the browser. I am running Windows 7 and she was on Windows 10, so we though that might be the issue. We followed the instructions from this thread, Captivate 9 preview does not work​, to set the default viewer for swf files to Internet Explorer and she was able to get the quiz to work in the browser only.

We realized afterwards that only the quiz questions I copied over were broken, but because we could get her browser preview to work and the project worked when published as HTML5 to our LMS, I left it as is. I have now sent the files for shared review in the Captivate Reviewer and am unable to get the Submit button to work (Windows 7 & 10 users alike). The .crev files are correctly associated to the Captivate Reviewer, and all the other buttons/actions on non-quiz slides work fine. Quiz slides on a pure responsive project work fine and quiz slides in a pure non-responsive slide also seem to work, but I'm stuck with my project...

Does anyone know of a way to fix those slides (preferably without having to recreate them all )? I have a feeling I know the answer, but am hoping for a miracle...

Thanks much!
