Looking around online I found someone had uploaded a playable demo for unreleased game early 90s Cyberspace. I downloaded and tried to run in Dosbox but get the error message:
"Error in AddObject: Too many groups"
Before the fame fully runs.
Any idea what the issue is? Because I have never seen this before and I cannot find it for searching Dosbox help guides or Readme.
I have done all the usual config, memsize changes and mounting checks and no changes I make seem to make any difference. I even tried moving the location of both the game files and my dosbox but I get the same message.

Adding on specific information needed:
