Installing DXKeeper 16.1.9 has corrected the earlier problem. Initially, DXKeeper would not open the kc1v.mdb I had placed in the databases folder or the config.txt file I placed in the Configurations folder. After re-selecting the config.txt file, both files opened. I'm not sure of the exact sequence of actions that caused the file to open, but at that point everything appeared to function correctly.
Thanks and 73,
