There are several things you can do in case of problems:
If you need priority support with guaranteed fast response time, please consider upgrading to the Pro version of Poedit. Personal support is part of the package and emails from Pro users go straight to the top of my inbox immediately.
You can also contact me personally at email@example.com (please include the word "Poedit" somewhere in the subject, together with a brief summary of your message). Or tweet to @PoeditApp (although email is probably better for anything more complicated).
