Problems installing gta vice city, i need hel pls!?

when i installed the pc dvd format og gta vice city i had no trouble. But when i was trying to play it it says wrong disc inserted. I copied the crcack from cd to the file location still the same thing is said. I opened the content of the crack file it says no mss32.dll found. I have a pirated copy but i dont think thats the prob coz i never had any prob with my other games.what did i miss?
