For last few weeks, since 1.8.0, I download it, and extract the files to the addon folder, just like I have done with every other addon I have to manually install for last few years, and it extracts the files, overwrites the old files and shows as if it was installed.  But when I login to WoW, version 1.7.5 still shows up on the header, and Oqueue does nothing at all.  Since then I have tried several other options for installing it found here.  Including completely deleting all Oque files so that nothing is on my machine.  Then download again and install again, only to get the same result, download and install v 1.8.3, and v 1.7.5 is what comes up in game.  I really like this addon, but it was much simpler when a client could be used.   Since I am having no luck, and from what I can tell from friends in game, many others are having the same trouble, all of us are now finding other ways to get a group for rated BG's, which can take hours.  TWO guilds are now out int he cold.  Time to move on I guess.
