I am having a problem with sw 2012 crashing for no reason. I will be working and all of a sudden the program shuts off. This started one day last week. I have had our IT guy check out the laptop I am using and he said everything was up to date. I am using this on a Lenova Thinkpad W520,with 8mb of ram, an NVIDIA Quadro 1000m graphics card, running Win7 x64. Need Help
