Whenever i've tried to restart my Mac Pro finder won't launch. I can click on all my items in my dock but after clicking on they unexpectedly quit. Right before the problem started i had installed magnifique and had just applied a theme. In the past few hours i have also downloaded and installed iTune statistician, iStat Pro Widget, iGenres, iConcertCal, However the problem did occur right after i applied the theme. Any ideas? Also I'm running Snow Leopard.
