Problems running grid2

I'm having issues running grid2 and I'd like to stick with that one as it's what I had in the past. It either doesn't get picked up by the game if I stick the main folder in my addons, or loads something basic if I put the 3 subfolders in addons (core, AoeHeals, Options) but then I can't configure at all ("you need grid2options addon enabled to be able to configure grid2").

Has anyone had this issue, and know how to resolve it? Given that changing folders around changes the behaviour, I'm expecting it's just the addon files not being in the right place.

I can't delete/edit my post. I found the answer right after asking here so I feel a bit silly, but the options are disabled by default and need to be manually enabled in the character selection screen.

Hopefully this helps someone else.
