Updated to 10.10.4 & No more Mail app...

[olletsocmit]

so i just updated to OSX 10.10.4 and restarted my Mac. I was scrolling thru the applications window to see if anything was new and noticed that the Mail app was messed up. The icon changed to a different icon and when I click it and try to open the app it flashes super quick in the bottom dock then closes.... does anyone else have any issues after updating to 10.10.4?

here is what the icon changed to after update:

Just updated ( via AppStore ) from 10.10.3 to 10.10.4 and no problems, certainly Mail App is still there
