You're not gonna believe this.......I got it going!
It was the only thing from the sticky thread that I overlooked & had not tried; replace the configdatabase.txt file with the one on the disc.
I'd like to say something at this point...if this issue was a common problem; and it certainly looks that way from the thread, then why wasn't it resolved in the download? See, a newbie (quite rightly) assumes the update, which is old now, works properly without issue. To my thinking, I would've assumed a copy of the offending file might be included in the download with instructions.....'Hey, if it don't boot up, try this'.....
Furthermore, a newbie is unfamiliar with the forum and its resources or where to find things, so nothing is easy, and understandable if one gets put off......I ain't a genius, but I know how to follow instructions.... even faulty instructions.
The many posts I made would've been avoided and the selfless efforts from some wonderful people here wouldn't have been necessary; I'm sure they have better things to do......having said that............is there anything else I need to look out for?
On a lighter note, I'm looking forward to installing sounds, a/c, skins, missions and mapping up the controls to see what this sim is all about. If successful, I'll even have a go at installing terrain from Wings Over the Reich.
A big thank you again to all concerned.
