I woke up this morning and now I can't use chimera. Everytime I try to launch it, it gets to the splash screen and says "cannot launch navigator. navigator is already running on this system. Only one version of navigator can run at a time." I am not running navigator. When I go to force quit, it shows only the finder. I have tried reinstalling both 0.5 and the latest nightly and throwing away my old version. I searched for "navigator" in the finder and threw away those files associated with the program, then reinstalled again. Nothing works. Help me please. Running on a Ti800
