With a little motivation and help from others, I have discovered the problem with the scripts you use. My game was installed in a directory that uses the "@" symbol in one of the folders . Eg " F: \ Games \ steam Games \ steamapps \ common".
When the mod searches for the eatglobal thingy, it cannot find it. This is because it's searching for this directory: " F: \ Games \ Steam Games \ steamapps \ common", which is wrong as it misses out the "@" symbol.
Upon reinstalling on a different drive that has fewer games to reinstall, and removing the @ symbol from the folder structure, the GT3 mod now works. I expect your other mods will work in future too. I hope this makes sense, as I feel a lot of my communication on this thread was maybe lost to translation in some areas. Hopefully this discovery will be useful for anyone else that might have symbols in their folder structure and finds the mods fail to run.
