@Tony Sorry, my time is limited, so I want to ask you kindly to answer my questions as precisely as possible.
I gave you detailled hints concerning the information that I need. You answered only vaguely a fraction of what I asked for, unfortunately.
For example I need the version number of TripleA to be found in the initital screen when starting TripleA:

Please point me directly to the posting(s) that you are talking about. I doubt that it will help though, as I have already explained the reason for the error to you. And that is why I asked you to provide screenshots of the folder structure of your map installation.
I am downloading this game from the Triple A desk top icon as well from this website.
The software and the maps can (or at least should) only be downloaded from the ‘official’ TripleA repositories. This website (a&a .org) does not provide any ‘official’ TripleA-related files. Sometimes other users upload something here, but this can’t be given support for, as TripleA development is a constant process with hundreds of updates per year.
I think each time I click on the Triple A icon from my desk top it gives me the newest version of Triple A.
No, it starts the software only. There is no automatical update. If you run an outdated version you will run it always - until you will update manually to a newer version.
This Map is found in the lowest quality Maps section or experimental section.
This statement clearly indicates that you have installed an outdated TripleA version as well as an outdated map file.
As the respective map works perfectly for me I can only work with the details you give me.
Also the hints and help I can give you depend on your detailled input.
