@Traiano, thanks for your help.
I have, using a trial Winzip, extracted the file named 'CvMainInterface' to my desktop and copied to 'GEM/assets' and also 'GEM/assets/python/entry points'.
It doesn't seem to be working, and I have tried the file independently in both folders.
Just to confirm, this is a .py file and the file is placed alongside the existing file 'CvEventInterface', although the new file (CvMainInterface) is 143KB compared to the existing much smaller 2KB 'CvEventInterface'. Is this the file I need to merge it with?
Also do i need to place in GEM/assets OR GEM/assets/python/entrypoints OR BOTH??
Thanks for your help, it is appreciated. The lack of a useful scoreboard is my sole bugbear with this awesome mod.
