Benjamin, can you please try my following suggestion before you try Raze's suggestion ?
Put the third cd (game cd) into your cd burner or cd drive.
I assume that you put the cd in your cd burner (because you wrote that you remove your cd reader).
Assuming your posted /etc/fstab please open a console an execute the following code as user root (you can try it also as normal user but I don't know if this works on your system)
Now open an other console an change to the "~/.wine/dosdevices/" directory ("cd ~/.wine/dosdevices").
Assuming your posting about the content of the "~.wine/deosdevices" directory you must now the the content of the game cd if you execute this command
or you change to the "d:" directory and should see now the content of the game cd.
If you use the "/media/dvd" mount point into the mount-command above (if you use your dvd drive) then the content of the game cd should be in "e:".
If this doesn't work, try Raze's suggestion and told me please if one of this two suggestions work or not !
