Crash/ won't run after upgrade 7/29/13 - version 1, update 13

After upgrading to v13 today, Indigo Studio will no longer start up.  I've been using multiple versions since its inception and this is the 1st time I've experienced this....

After receiving an email about theupgrade, I launched studio... was prompted to update the Updater....did that.  Then finally was prompted to update to update #13.... which I did.  All seemed to go as expected... but then the app will no longer fire up.   I get the splash screen for a couple seconds, then poof.  gone..
