Crashes at start up

I just recently updated my MBP to Yosemite. So I downloaded the latest version of Adacity and reinstalled the application. But it crashed at start up. (The icon appeared for a second on the dock then disappeared). Help!

Please see the pink panel at the top of the page and give us the three-digit Audacity version number. Make sure you have Audacity 2.1.0 from
