I downloaded Daggerfall from Bethesda's site and proceeded to install it with DOSBox per the instructions provided. It worked, then worked again later when I followed the instructions for playing the game again. Now, when I enter those commands, DOSBox tell me that I "must have inserted the wrong disc". I tried twice more, perfidiously ensuring that I entered exactly the correct commands, and it's not working.
I apologize for any bothersomeness that I may be providing to you, and a thanks-in-advance to anyone who may provide me with a bit of assistance with my problem.
