HI Argent77, unfortunately I cannot use the latest versions of EET (13 and up) as they are designed to work with OSX 10.15 and my dusty old machine won't run anything beyond 10.13. But thanks for your input.
Graion, I know little about modding so a lot of what you said is beyond me, I'll try the version in your link later. Whatever the outcome I truly appreciate your efforts.
I am not sure if this makes a difference but I have managed to install EET V 12.2, I had to edit the tp2 file so that it would recognise the proper exec. file, but when I launch the app I do not get the menu option to select a campaign. All I see is the usual BG2 EE main menu offer SoA, ToB, and the black pits.
Thanks all, Ill report back once I have made another attempt.
