Plugin Files Last Working

Hey this is for the author or anyone that can help. I have been using this pluggin on one of my sites and now need to move the site to a different server. However, I have never backed up anything and I do not have the original files for yak. Is there a way to get the files from what I have installed or can someone provide the link to download the initial install of the last working version before it was discontinue. Sorry I had no clue it was discontinued.
