I installed The Sims Deluxe on my Vista laptop and it will work for a little while but during the game, it crashes and takes me back to the desktop. I haven't downloaded any extra skins or anything else, I only have the files that came from the install cd. Is there any way to keep it from crashing unexpectedly like this? My system specs: AMD Turion64 2.4GHZ, 768MB Ram, ATI Radeon Xpress 1100, Windows Vista Home Basic.
