Make sure your catalog folder and .mdp/.mdc file have the same exact name. i.e. AdvanceWareCabs (folder name) and AdvanceWareCabs.mdp (filename).
To find the folder for the .mdp file, follow this file path in your File Explorer: C:\ProgramFiles (x86)\Advanceware\Catalogs.
To find the folder for the .mdc file, find the path in your QCC TOOLS menu under QCC PREFERENCES...
NOTE: The .mdp file will be located inside the catalog's folder. To find the .mdp file more easily, filter by Size.
