So I had acquired the Aux-addon from another vanilla add-on site. It worked just fine.

I tried changing my auction house add-on to Auctioneer. Found that I didn't like Auctioneer as much as Aux. Deleated Auctioneer and re-added Aux to my \Interface\AddOns

Since then I cannot use Aux in game and I get the attached error:

Any advice on how to fix this error? I have tried removing and re-adding AUX. I am using the aux-addon-master from this github.

Thanks

Delete everything related to Aux in your WTF folder.

I'll give that a try

IT WORKED!! Thank you!! Note: I also went through and deleted the info from all my toons.
