What you have to do is hack the main Sims 2 server records {don't woryy it's easy, even a caveman can do it} first open up the secondary router links then access the d drive in START. transfer the secondary drive to the d drive and now you go to D and open up the file and your in. find a box to type the access number 3xw14y. this will allow you to move around the drivers of the game. you need to move the driver 6745 behind driver 2231 and in front of 1289. now this should have opend up some space and you should be able to load it onto the file access pannel GAMES. load it and then restart your computer and it should work
That is one crappy and WRONG answer. (Dont even try to understand that because they didnt know what they were talking about and just trying to confuse you) I am having the same problem with another program. Yet I cant seem to find a good answer for this answer for this. The best thing I can advise is to uninstall and re-install the program that is crashing.
ANSWER
