Sibelius stopped working.

Sibelius was working fine up until about an hour ago.  Don't know what happened, but it will not open.  I'm using a Mac computer and when I click on it I see the logo on screen and that's it.  Hope someone can help.  Sibelius is literally my life.  Thank you.

It's working.  No need to reply.  After about an hour of it not working it finally opened.  Don't as my why, but it really had me worried.
