Mission editor problem

I used the mission editor once and it worked fine in windows 10. When I tried to run the sh3 mission editor a second time I get an error message 'The unit class CDAAPlatform from country Brazil not found in the platforms library.

Has anyone else found this problem and know a solution?

Alternatively, is their anywhere I can download it directly and put the compatibility patch over it? I don't really want to uninstall and reinstall the whole program again.

Thanks in advance!

To those who viewed, thank you! I am very grateful to fahnenbohn who has offered to help solve my problem

For anyone who might experience a similar problem, the source was traced to a small error in a mod I was running that removed land units from the SH3 game code.

Many thanks to fahnenbohn, I learnt an astonishing amount in a very short time, mainly to do with me being a dunce...

On a side note, I can safely say that in the short time since I've subscribed I've found this to be the most inclusive and welcoming forum I've come across and with a huge willingness to share knowledge and experience. So thank you. Its all rather humbling. Probably deserves a round of applause
