Everything - in all documents in Pages is locked suddenly!

Hi, I have been working on a bunch of signs and saving them as 1-page documents. This morning I was working on one on my iPad, and I changed the spacing between the lines of text in a text box, and it gave me the plus sign at the bottom. So, I tried to drag the box down to make it bigger, but I couldn't even grab it. I tried to undo the changes to the line spacing, and still nothing. So I tried to move the box, and I still couldn't grab it. I could add other elements to the Kate an doormat them, but couldn't resize any of them. I opened up some of the previous documents I had created and they all were the same: locked.

I have a fairly new iPad and don't use it often. I have iOS 6 installed and jousts installed the Pages app less than 24 hours ago.

Oh, and I need these signs by tomorrow morning.

Help?
