Hello,

In this case you were suspected of using the FREE licence for a commercial purpose which is considered as a violation of our licence policy. We informed you with an email notification but after you refused to answer, we deactivated your licence. If this is a misunderstanding, please contact me at: markosky@emclient.com with an explanation.

Thank you for your understanding.
