I downloaded the addon and it worked properly.
I then downloaded https://wowinterface.com/downloads/fileinfo.php?id=25941 and it worked properly.
I logged out and back in and now the background of all the screens are grey, dungeon finder/character panel etc

i have uninstalled and reinstalled the addon and deleted and repasted the elv ui texture pack and nothing works to get the addon to work properly.
any suggestions to get either both to work together or at least the addon to work again.

I installed that texture pack, but I'm not getting this issue. Check the backdrop opacity in Aurora's settings.

Closing this due to lack of response.
