Pages 09 - spellcheck / proofreader not working

Hey,

Spell check has stopped working on Pages 09. It doesn't check the text and doesn't launch when directly clicked on. This is the same for proofreader too. I have gone through forums and tried all the answers I found including copying and pasting text from text edit, deleting my pages preferences in the library, selecting text and changing the language in inspector, relaunching etc. Nothing seems to work. Its like this entire side of the package is not working. I can't figure it out and need to get this up and running for a paper. Could revert to word, but I bought pages 1 month ago and am loath to revert if at all possible. Any assistance gratefully welcomed.

Kind regards

Andrew
