Licence problem

Hello, 
when I start the eM client it sayys that I have invlid licence. I used your page to retrieve my activation key and I got back my activion key with expiring date 1.1.2016. When I put the activation key into the licence it says that is invalid. Can you help with this problem asap? The  email adress is penzion@villaregia.sk

Hello, I’ve checked our licensing, but unfortunately it seems like your license has been blocked due to suspected commercial use activity, please obtain a valid PRO license at http://www.emclient.com/pricing in order to use the application further.

Regards,
