Older version not loading - Need pause button from 1.3.3

Hello there, I’m gonna run CoCT Chapter 3 tonight and the Queen’s speech with the Marcus Endrin stuff etc and I’m using the soundset as a background when talking as the Queen. I wanted to use the “pause” option we had in the previous versions so I tried downgrading it to 1.3.3 or 1.2.8 but the software is now in “loading” forever and not starting at all.

Of course if I upgrade it to the latest version it works again but I really wanted that pause option so that I could describe the situation in details (the Endrin moment is really fast and doesn’t give enough time to describe it)

Thanks for your help, hope I can fix it and use some sort of a pause option!
