GoW judgement Campaign mod tool error

Hi everyone, got a quick question- im trying to R&R my GoW:J campaign save i just made and its not letting me. its giving me an error msg saying that i cant save because the file is open in another process, yet horizon is the only program that i am running right now. how can i fix this??

I suspect you’ve got another process open somewhere or you’re trying to copy the save to the usb without using Horizon. Also if you modded it with another tool, that tool might still be open so it would cause the same type of error. Hope this helps. Enjoy the game.
