timemapper buffering not loading

Hello, I created this in tribute to my grandparents when I returned to stufy a few years ago, but i just noticed it will not open and I do not have a clue how to resolve this. I would so appreciate any guidance on this, thank you. Nina.

Looks like I will have to build it all over again, I cannot find the google doc it was based on sadly.
