Okay chaps....I just don't know what the problem is
I did the above, installed a Vanilla 1946. Ran the game and it got to the menu...5-seconds later CTD.
Tried this next:
Copied the contents of my fully working HSFX 5.01 install into a new directory. Ran JGSME and downscaled the game to stock 4.101.
Installed 4.11 patch.
Game gets to menu then CTD
Dunno what the problem is, but looks like I'm just going to be flying HSFX 5.01 and not see the beauty of 4.11
Thanks for the input though, cheers, MP
