Hi,:wave: thanks for the view. I bought a grand theft auto vice city installer from mall.Then when I arrived home,I going to install it. The installation disk I bought has 2 installation disks. according to the installation instructions, the Disc 1 is the "main installer", and the Disk 2 is the "Play Disc". Then I installed it. In the middle of the installation, a error message occured and tells me that I must insert the disk 2 of the installer (the "play disc"). so I inserted it, then it continued installing. when the installation completes, it said that vice city is now ready to play. but when I start the vice city, error message occured: "No disc Inserted, Please insert the Vice City Play disc." the error message refers to the disc 2. so I inserted the disc 2 (play disc). but everytime I load the game, same error message occurs. can anybody please tell me what's the problem of my PC? thank you and i'll be waiting for your reply.
