No matter which key I copy and paste, I get a message saying it is incorrect. I have already written about this and asked for help, but I haven't managed to resolve it. Consequently, I can only perform actions that can be signed using Hivesigner. When I first started here, I didn't know anything, so I set up signing via Hivesigner. I didn't need my keys for a long time, but when I finally wanted to use them, I got a message saying they were incorrect.
