How to get rid of ox report client messages?

Hi ng,

we installed the OX Report Client (containing our license key) and we installed a cronjob too. We tested the submission and everything looks fine. However, every 2 or 3 days we're getting a message from OpenXchange that our download-account is blocked.

What's wrong?
