Shop and Ranked Chat Problems?

I joined a ranked game it it just so happened that I couldn't see chat. At all. If i typed and pressed enter it would act like it went into chat but nothing. Just nothing. And then while waiting my 5 min for dodging, I came decided to stop at the store. It would take me to the featured page like normal and would change pictures and such like any other time. But if I click any button at all I get is the "session expired" page and then go back to the first page. Literally any button. Even if I try to re-click the featured button. HELPS!

(I'm also on a mac client... QQ)
