BTW, I have read where V. 20.03 is not something you want to run. It was like an experimental version or a beta version, something like that. I believe I read that if you use 20.03, then only 20.03 can access it, nothing higher will open it. Hope this will help you a little bit. Have a great week.
I tried following that thread already. Seems he is having somewhat of a different issue than me. I have also tried uninstalling and reinstalling the AOP and EDS Files for that module. Seems to be the only one that this happens on.
