Well, we don't know exactly what you've done as your information is poor. But probably, yes to both questions (so far as I know).

Did you ask someone to install a modchip?
Have you asked them which modchip they installed (very important)?
Did you do it yourself and if so which one did you think you were buying?

You need to know this stuff in order to know where to go from here. Also:

Have you got a CD burner?
Have you downloaded CloneCD to make 1:1 copies using a compatible burner?
Are you able to search the net for yourself to take yourself as far forward as possible?
How is your English?
