korell: Well, I got another reply back but again just asking me to run via the shortcut/GOG link.
I decided to re-install it to give it another try anyway, and this time it worked. From the GOG shortcut on the desktop, the Start menu entry and from the GOG .lnk file in the installation folder.
I then applied nGlide 1.04 and it still worked.
I also noticed that this time the lee____.ttf file got locked after playing the game, so it found it this time.
The only changes that my machine has had since I last tried playing the Nitro Pack are:
Star Wars: Rebel Assault 1 was installed, played through and uninstalled.
Apple's Bonjour program was uninstalled from my machine (no idea how that got there as I don't use Apple products).
GOG Galaxy Alpha was installed a few days ago, too, but I didn't use it with I'76.
Can't see how any of the above would have made any difference. Strange.
That's so strange. At least it worked in the end.
Did you run the game from the installer the first time? I wonder if something needed to be in "run as admin" mode.
