Can't Download Appchan X

[Keyosu]

Whenever I click install Appchan X I get this page https://gyazo.com/58e02cbd90f650ff65d7897f1158228e I have installed greasemonkey and disabled adblocker. When I click install it just brings me back to the main page and nothing happens. I've also tried clicking on the firefox symbol below to make sure im downloading the FF version. I believe This was after the new firefox update since it put my old profile (where Appchan worked) in the Old firefox profiles folder and restarted everything fresh.

Update: When I click on the greasemonkey icon in FF it says appchan x and that its enabled but when I go to 4chan I don't see anything different.
