I had problem with my machine, so i recover the system from the recovery partiton, everything back okay and fine, except Mail Application,
when i start mail i get this:
"Mail cannot be opened because of a problem.
Check with the developer to make sure Mail works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X.
Click Report to see more detailed information and send a report to Apple."
Any idea how fix this, and run Mail,
