I have an HP Entertainment Series Laptop with 2GB memory and hardly anything on it except for Microsoft 2003 Office. I have XP. I loaded a game called Strikeforce on it for my son because his computer only has 1GB memory and I though he could play it better on mine. It loaded and when he went to play it it said "not enough memory". I don't get it. I have pleanty of memory. Any suggestions?
