I want to play iso games but

kso i downloaded an iso game and i have it installed. But whenever i try to play it it says wrong disk, please insert proper one. it says i hav to use disk 1 but i mounted it and used it but it still says wrong disk.

HELP!!! plzzzzzzzz

If this is a pirated game myan89, forum rules prohibit such discussions. Sorry :cop:

how do i no if its pirated?

Where did you get it from? did you pay for it? is it available from the developer as a downloadable iso?
