How can i fix this? Thanks in advance. Greetings Jonas February 7, 2020 at 12:34 pm #12211 dougModerator This bug was fixed in 2019.10.18. I assume you are using an older version. Try closing all instances of BP and then delete HKCU\Software\BatchPatch\Email\SMTPPassword or update to the latest version.
