Iv had 2 updates in the past week, what did they contain?

I can't load anything, all saves are gone and I was at the end of the game! I haven't played in a while, and I am using a different computer but that shouldn't make any difference. This will mean I can't finish the series, after all that time put into it. How can they just disappear? Any suggestions? I have Windows 10 and it's a desktop. I'm wondering why they're updating so much and could that cause this problem? I don't know much about computers unfortunately. Thanks for any help! This is very upsetting....

RIP (Actually , i just realized this game is in a package. How foolish am i).

When i started the game, it gave the error "couldn't load pointlight2d"

Hello community, a particular question. I'm a Streamer and I can't get the game on the OBS, I don't know if it's because of its age and it's not compatible. Can anybody help me? Thanks. :)
