a valid licence could not be found. Why?
until 28.4.19 I had no problems but since then I can´t receive or send mails. Thunderbird says " a valid licence could not be found". How do I get a valid licence?

Thunderbird is free software and doesn't have a license. Please post a screenshot. https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem
