I'm sorry, I don't know much about computers. I don't know what an objects error is. If it has anything to do with Simpe...guess I am in trouble because I have never used it. Also I don't know how to add attachments. So never mind I guess...just thought there might be a fix for this.Thanks anyway.
You can find the error log by simply going to My Documents, EA Games, The Sims 2, Logs.
