failed to launch

I did not get any Failed to Launch errors that led to the "fix" on March 23rd, however, after that "fix" I am now getting that error 10-15 times a day.  I have tried all the fixes suggested such as dragging folders around, clearing caches, playing without mods.  Nothing works.  If I clear my cache and play without mods my game works for a bit, randomly shuts down, then fails to load.  I have to reload 5-8 times to get it to load.  Once it does, I must then exit to main menu about 3 times to get the game to unfreeze in live mode.  No, I do not use custom content.  I used to use mc command center but since this issue I have deleted it from my computer which blows since my favorite form of play is rags to riches.  Most of the trouble stems when coming out of or going into CAS.  I can pretty much count on a crash followed by 5-6 failed to loads before I can play again every time I use CAS.  The only way to reliably change a sim's outfit is to go to neighborhood view and manage households.  If I do not do that then the game crashes when coming out of CAS and all the changes are lost.
