Palettes have all disappeared!!

I’ve just opened a project I’ve been working on for ages and all the colour palettes have disappeared and everythings greyed so I can’t import or create a new one.
I can see the .plt files are all still in the right folder structure but I can’t access them.
Also some customised keyboard shortcuts are working anymore tho I don’t know if this is related…
Help please!

Doh! Forget it. I just solved it…
