LUA Error with right-clicking Ask Mr Robot add-on icon

When I right-click on the addon I get this:

Message: Interface\AddOns\AskMrRobot\Gear.lua:1224: attempt to index field ‘?’ (a nil value)

I saw the reference to the other addon, ElkBuffBars, so I tried disabling that and then the same error showed up but a different addon was in its place (grid), then I disabled that and another addon went into its place. So I don’t think the problem is with another addon.

Try left-clicking on it instead, so that you can see the user interface, and then re-import all of your setups from the website. That should clear it up I think, then right-clicking can be used to cycle through them again.
