Help getting information from game client into gear optimiser

I downloaded the latest AMR client (v63), but when save it into Interface folder on my computer and open game, the Export screen in game tells me that v52 is current version. When I go to paste string into website, I get told I have an older version of the add-on loaded.

Please help - getting frustrated.

Just to be clear: the simulator client and the in-game addon are different things.

What you want is the in-game addon from here:

You can also keep it up to date using the Twitch App.

Make sure to completely exit WoW also.
