Spellcheck problem in Outlook

[Karenlsinging]

My spellcheck facility doesn't seem to be working properly. When I do a spellcheck on an e-mail I know has mistakes in it I get a message telling me that proofing tools for Welsh are not installed even though my language is English UK and my Tools Options Spelling tab shows English UK.

If I say OK then it tells me the spellcheck is finished and there are no errors when there obviously are!
