I am a builder in SL and when I try to use the lighting feature on an object or try to edit a lighting object the program closed immediately. I tried to fix this problem by restoring my computer system but it didn't work! when I re-Install the program it doesn't give me the original settings like they were when I Install SL the first time. *Is there a way to Fix this problem without re-installing SL or restoring the computer system to an old restore point? *Is there a solution to return the program, such as the first time I installed it in my computer (edit menu, tools menu, advanced menu and all other menu bars are all restored to the default settings) ? I hope there is a useful solution to my terrible problem
