Was prepping for game and placing lights. When I placed a second 120' light not tethered to characters the game froze up. No I am unable to initialize campaign. It loads for a very long time (initializing) and then gives me "please wait" message on black screen. I have waited up to 2 hours to see if it initializes but no luck. I am able to create new campaigns. I tried deleting the campaign, starting new campaign of same name, and then replacing files with (backed up) original campaign. Any ideas?
