SMM won't open after crash.

Basically, I went to download a new mod and right when I clicked on it in SMM, I blue screened. After restarting, I'm now completely unable to open SMM. I keep getting the same error message: "Failed to initialize ficsit-cli:failed to initialize profiles: failed to unmarshal profiles: invalid character '\x00' looking for beginning of value"

I have no idea what this means and I have no idea how to fix it. Any help?
