I just reloaded my game after using the first link posted and this helped me fix my issues. now I see a full spread of players using OQueue
https://solidice.com/icebox
makes so that you can click the desired upgrade and accept upgrade.. allow the system to make 'changes to your computer' and it will all work out. also if you have wow loaded close it completely and then open it all again.
this worked for me THANK YOU SO MUCH for the help and your prompt reply to my querry
