Cannot open up the in game shop

So recently (yesterday) i started a draft game, everything went well whatever until everyone loaded up, I wanted to buy an item but the "p" command opened up the little stats tab next to the champs portrait... I checked my key bindings, everything was where it was supposed to be. I even reset the keys to their default settings.

When i clicked the shop, same thing; stats list.. Has anyone run into this problem? is it a bug? Might reinstalling help?
