I'm desperately in need of some help with my windows 8 mail app. Mine is a Sony Vaio and I've just bought it a few days ago. At first I synced my gmail account to windows mail and it was working okay, but then some problems with sending mails started to appear more and more often so I removed my gmail account in order to 'refresh' the app. However, after removing the account my windows mail isn't even opening anymore. Whenever I click on the app, it loads for a while and then the screen below appears:

 

So it's basically the mail app itself with nothing inside! I've tried to click every button but nothing worked. I've restarted/shutdown but it didn't work either. So I tried to recover the whole computer without affecting my files, but then the system said 'There was a problem recovering... No changes made' or something. 

So does anyone have any idea how to fix this? The mail app is the one I use most on my laptop so it's really frustrating that it stopped working out of nowhere!

Thank you so much guys, any help would be very much appreciated. 

Have a nice day!
