There's no version 5.1.9, did you mean 5.9.1? The latest version is 5.10, please update.

Please make sure that you're using the latest tweaker version. If that doesn't solve the problem, please provide your tweaker version, the version of your explorer.exe file, and the exact error message that you're getting.

Fixed in v5.10.

Changed in v5.10 per your suggestion, thanks.
