Toon Boom Studio 6.0 - Not remembering keyboard shortcut preferences?

Hey, I just recently purchased Toon Boon Studio 6.0. This may seem like a minor issue, but when I customize the keyboard shortcuts, it works for the session, but after I close out and reopen the program, the keyboard shortcuts are reset. I could not find any discussion of a similar issue, so I was wondering what the problem might be. Thanks.

This could be due to an antivirus program or security settings that lock your user’s Library profile files (Mac) or the registry (Windows).
