Well I just upgraded from like 4.5 version of seti menu and version 6.2 wont launch. I'm running 10.3.3 and 6.2 just does nothing, I launch it and i get nothing. I even tried redownloading with no change. If your upgrading to 6.2 DONT DELETE YOUR OLD VERSION you might need it.

GUI for the SETI@home command line client
