Are you having problems ejecting the disk, or getting it to register? For ejecting: Type into the terminal 'wine eject d:' (replace 'd:' with whatever drive the disk is in') For getting the computer to register that the disk is in: Try opening the disk in a file manager, (e.g. the windows version would be 'Windows Explorer') that sometimes gets the computer to realise that there is a disk (with information on) inserted. Then keep clicking continue until it does what it's meant to. Hope that helps!
