i burned a two cd game using nero.. after the first cd installs it says "please insert disk 2" when i insert disk 2 and click ok the dialog box goes away for a few seconds and pops right back up.. after that i can click ok as many times as i want and the dialog box just keeps popping right back up.. any ideas?? it seems like the disk drive is not seeing the cd... but a window will pop up with the cd contents.. i'm at a lost.... please help
