I\ve noticed many people on this forum are talking about GSOD, i guess they are meaning Gray screen of death, i\ve had this aswell wth linuxmce,
but i did NOT have to reinstall anything as many of you mention.
Remember the webinterface normally comes up, atleast every time i\ve had it.
But the web interface might take 10 minutes to start.
I guess, GSOD comes because of ui2 not working, try changing back to ui1 on the Media Director site on the pluto admin page.
Just a possible soloution other than reinstalling the whole thing.
