Well I was sending email to a friend and wasn't sure of the spelling of some of the words so I did spell check and that's when I got the little window with the message saying that(english) language was no longer avaible for spell checking. "Please select another in the spelling options dialog."
Start Windows Mail
Click the Tools menu and choose Options...
Click the Spelling tab
From the Language drop-down, select English (default choice)
Click OK
