Can't read RCT2 files

[M51]

I just discovered OpenRCT2!

I have an original RCT2 cd-rom and both expansion pack cd-roms. I would like to extract the needed files from the original cd-rom, but when I insert the disc I only see a couple text files and a bunch of wav files, all with non-latin character names. I know this disc is (was) good because I used it to play on Windows, but I no longer run Windows and am trying to extract the files under Debian 8 (Jessie).

Any ideas?  Thanks.

Nevermind.  A reboot solved the problem.

That was weird.
