File Load Error

Hey! :slight_smile:
My team and I are developing an RTS game, because of our reasons, we opened new UE4.8 project with the full game project backup.
So we got something about 80 file load errores.

Someone knows how to fix this?

Thanks!

How have you converted your project to 4.8?

Yes and then we save it as backup and opened a new 4.8 proj with this backup.
