Re: Sims 3 Gives me an error code. (0xc0000022)

Try running ccleaner on your system to clean your registery. 

Is Sims the only program you have issues with ?

Did you change anything on your system when it stopped working ?

Might not  be a Sims issue as such. When I googled the message they all said it was a Windows issue and most likely has to do with corrupt registry entries.
