Hello, I have a developer account and downloaded and installed OSX Yosemite. Since I upgraded to Yosemite I haven't been able to open Mail. I've searched around the Internet for help and I can't seem to find anyone else with this problem or anywhere I can get support for it so I figured I'd try here. When I try to open this program a window pops up and says: The last time you opened Mail, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again? If I hit either "Don't Reopen" or "Reopen" I get a huge error that's apparently too big for this post saying "Mail quit unexpectedly" followed by a ton of code and stuff I don't understand. Has anyone else encountered this or know how I can fix it? I use mail all the time and not being able to open it is making checking my email a lot more awkward. Thanks in advance for any help.
