Mail crashes upon start up
I just upgraded to Mavericks yesterday and all went well. I installed the Mail update before opening Mail 7
When I opened up mail I went thorough the setup window and the progress bar began download my messages. This actually took longer than I thought I had to force quit mail before putting my system to sleep
Now today every time I launch mail the setup window comes up, I hit continue and Mail instantly beach balls, the setup window disappears, and mail is non responsive.
I've tried restarting and reinstalling the mail update but it still won't work.
Any suggestions?
