License deactivated

Opened em client up and it is offline with a licence error. I tried to reactivate it and it says contact support.

Hello Paul,

If it’s a free licence violation error, send me please your licence key to markosky@emclient.com

Russell-
I have the same issue. Did 30 day trial and then got license for free version. It worked for about a week and now it does not work.

How do I get a new license or fix this one.

Thanks
