keine gültige Lizenz

hello, seit Tagen arbeitet eM Client nur offline: pop-up erscheint mit meldung "keine gültige Lizenz etc.etc… Bitte um Lösung des Problems

Dear Sirs, please help us with the reactivation of our em client. At the start it says “this computer cannot be activated due to violation of our license policy.”
As we are using only one E-Mail account with your client, i do not see any violation to your policy. Please set our license free and contact us: morgan22@utanet.at

Hello all,

Please send me an email with the activation key to markosky@emclient.com

Thank you,
Russel
