I was trying to install Age of Empires III through PlayOnLinux, and everything was working fine. I entered the path for the disk, but when it asked me for the second disk, the paths weren't working.
I had viewed the contents of the first disc in Nautilus, but now, after stopping the installation, I can't see anything with Nautilus in the CD. I have no idea what happened. If any information is needed, let me know and I can get it for you.
I did just upgrade to 12.10.
