Insimenator.org

Before I installed AL, I disabled all of my hacks and mods via clean installer and then when I found updated versions, I added them back in, including the updated Insim. When I managed to get the game running, after one aborted attempt(I forgot to delete the cache files), I decide to delete some objects that I no longer wanted, to improve my loading times. I had deleted about half a dozen items and then an error box appeared, telling me the application had crashed and was being terminated. Is this because I was deleting objects "in game"?
