I have bought a regular license (about 2 years ago) but now the plugin says that the license is expired or not valid.
I cant send email through feed-by-mail from about 1 month (the only way we use to send newsletters). I Tried to debug everything.. Last your plugin and extensions. May it block sending due to license issues?
I can provide license code if necessary..

Thanks in advance
