Ahhh! It finally worked again. I don't know what command finally did the trick but a pop-up
"Running wine-unity3d-installer" finally appeared and now the game loads.
First I did the command you recommended:
sudo pipelight-plugin --create-mozilla-plugins
I tried switching different browsers through the UserAgent and ran these commands again:
sudo pipelight-plugin --update
sudo pipelight-plugin --enable unity3d
So is there a specific order to run these so it will work first time?
