Your Saved Games folder might have a corrupt file in it but also contains a lot of things that are hard to replace. This is why you want to create a backup, delete the original one, start DCS to create a new one, and then copy and paste only your Config folder for control layouts , Missions ( downloaded ones), and weapon load outs back into your new Saved Games folder. Sometimes Options LUA is a problem so it's best to not copy that back in.
