Old version zip file?

Hi. So, I tried to update this plug-in from an old version and it completely crashed my site. I had to go into the files and delete the plugin. The new version doesn’t seem to work with my site at all and I can’t even get into the back-end of WordPress with it in the plugin folder. Can I get a zip file of a pre 1.17 version? I looked at your Github but, if I’m honest, I have no idea what I’m supposed to do to get the correct files from there. Thanks in advance!
