Chat glitch! Cannot type the letter P -RESOLVED!

[Jacarius]

Heyo!
It's that simple, I can't type the letter 'P' in game at all. Neither can other users see anything.
It's not even that the P is invisable, it just doesn't work. So if I don't add a space or an underscore ("_") as I've been using to role-play, my words look like this:
Rolelay, role_lay. Tpe, T_pe and so on.
It's become very urgent because explaining the glitch takes up a lot of room in Movie Clip and when asking to join packs. (
Hello, may I _lease jon your _ack? Would you like a R_ ample?" xD)
Plus my posts end up riddled with underscores!

So I've re-started a few times, logged out, but I'm totally out of ideas on how to fix this, help please! ^~^

You could either reinstall the game or Change the render system, notify me if it works.

Ah thanks for the help!
I changed the Render and nothing happened, because, it seems it wasn't a glitch. I made the mistake and changed the controls and the letter P had been put as the Print Screen button, (witch doesn't work on Mac laptops) so it did nothing and wouldn't work as a letter in chat! I just changed it back around to the default and everything fixed!
