All of a sudden my OS X Mail APP will not open anymore. I didn't do anything other than restart yesterday but it will not open. All my prefs and mail files still existing in my users/library/ directory so those seem fine (I think) but the app will not open. I double click on it, and it acts like it is going to open but then just does nothing. I got a fresh copy of mail.app from a friend but that didn't make a difference.

Any help would be tremendously appreciated,

And btw--I already looked at this threat

and it wasn't any help.

Thanks again

You probably have a corrupt preference file.

Move the file ~/Library/Preferences/com.apple.mail.plist aside and see if that fixes it.

Hold down the option key while launching the app. Worked for me when I had the same problem.
