I've downloaded JA: Deadly Games to my MacBook running 10.13.6. I watched a tutorial on YouTube, and used Wineskin to wrap the files in a way that would run on my computer using a DoxBox type program. Specifically I'm using Boxer which has worked for other GOG DOS games in the past.. However, when I attempt to run the file "dg.exe" from the Dos prompt I get an message:

Error: Problem reading CDRom. Please check.

I scoured the internet for similar problems but I've been unable to find any solutions.

Any help is appreciated. Thanks.
