As of this morning (8/24) the desktop app doesn't seem to want to load. I can access my assets through the website and through in app panels, but the desktop app just shows the wheel of death and never seems to load. Nothing has changed on my end other than the most recent OS X updates. And I loaded them Friday and it didn't seem to affect anything right away.

Reloading the software and restarting seemed to fix this issue.
