Rimes App Server is fixed

We've occasionally ourselves got in known, that server of our Rimes Generator was down for a few weeks. None of thousands of our users wrote us about this issue. But a lot of users thought, that their duty is to put the app 1 star.
Folks, the task is maximum simplified: To write. A single. Email. Right. Through. Your. Phone. With. For. Words. "Rimes App Doesnt Work".
Is it very hard?
