Last night I installed the Security Update 2012-004 for Mac Os X c 10.6.8 and then shut down my computer. This morning when I opened Mail (v 4.5) I got the message per above. I have since followed the above instructions - the new Mail program 4.6 was already in my Applications folder.


Any other suggestions? Have already lost 3 hours on this today and still no access to Mail.


Thanks in advance for any help!
