Latest build is not working

I updated to the latest build and RetroArch just sits there. Joypad is unresponsive. Only the arrow keys on the keyboard are detected. Can’t even exit RGUI, have to cmd-Q. Clicking on Go>Cores Directory has no effect whatsoever. Editing or wiping retroarch.cfg has no effect. Deleting preference plists has no effect.

Is that the 10/29 build from the buildbot?

I don’t know. They are dated 01/19/2015. The contents of the cores directory and retroarch package are dated 10/15/2014.
