I know there has been alot of glitches and error codes, I am now getting the error code 14 and 12 and lost a whole days worth of work, my bad for not saving. If anyone else is having refresh problems where everything is grayed out for short period of time when they go from upstairs to downstairs or going to the neighborhood and it sometimes takes forever, so I decided to upgrade my memory to 4 gigs and boy did that solve the problem, the objects just pop right up and it has really helped 99%. Still a second or two lag but not at all like it was before. I have the biggest video card so I knew it was not that. I can't say for sure if that will help everyone, but thought I would pass along this info. If it can help in any way for someone else's playing, then I am glad it helps. We have to understand, the bigger the game gets the more memory it is trying to process and bits and pieces go everywhere, if it has no where to go, then it is going to hang. We all have spent tons of money on our games and if some little thing helps, then I am all for it. I, like a lot of people have played sims since day one with every expansion and stuff pack, in spite of all of the problems with WA, it is an awesome game and I do not regret purchasing it all. So if this helps someone else, let me know.
