Receiving a licence violation message , asking for license. Unable to send & receive email. 

Me too, can someone respond please

also received the same message yesterday, help

Same problem here, using free version.  Suddenly saying there is a licence variation. Help

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.
Russel
