Can't switch my spells.

shindenial

So I leveled to 30 and 31 today. When leveling to 31 I of course went to spend my points under my Power tab. All that came up was a picture and the message that I have "Achieved mastery in the skills of a Control Wizard! You may now choose a Paragon Path." Ok, um, I did that at level 30. I want to switch out my spells but the screen that HAS all of my spells on them is GONE. Just that lovely picture and message. I am assuming something is not right and that I am NOT stuck with what's on my current action bar, tell me this is so.
