Oqueue 1.9.7 works but not 1.9.9

I tried updating my oqueue addon to version 1.9.9 and i downloaded and dragged in into my addons folder. After that i logged into the game and checked to see if it was there but sadly it was not there. So, i decided to drag my old version of oqueue back into my addon folder to see if it was working and i logged in and it was indeed working but not the new version. Please fix this ASAP. I have a Mac.
