I'd try to actually install from titanium cd's. Barring that you seem reluctant to supply much specific detail about your setup. Maybe it's just a language barrier misunderstanding, and I don't mean to sound rude, but without any technical info technical support can't be forthcoming.
Without more info about your computer we could guess all day about what caused it. What Operating System, what video card, what drivers, what processor, version of directx....
Look at other posts for the kind of details needed if you don't know.
