Spell Check Not Working on Office 2011 for Mac (Word) from Today!

Help please

Jumped on my Mac tonight to right a report in Word (2011 for Mac), been using this before Xmas and in years past other Office for Mac versions. Never any problems with the spell check before i.e. red wiggly line appears so you can review or amend as necessary, but no red line tonight!

I have being playing around with the settings > preferences > spelling - I leave the "Hide spelling errors in this document" unchecked, but still it dosent seem to work anymore.

I am the only person who uses my Mac and I haven't changed any settings so I can not understand why this is happening now.

If anyone can help, please do as I miss my reb wijgly anb mi speling is rudish without ip!

Thanks John
