Hi having problem playing ghost recon. Installed fine but when I click to launch the game it says "Please insert the Ghost Recon CD-ROM, select OK and restart application" but the CD-ROM is already in the disc drive. Am running game on windows vista Acer aspire 9300, AMD turion 64x2, 1.6 ghz, 1023 RAM, NVIDIA 7300 graphics card, 128mb. Thanks
