Hello, have error - this computer cannot be activated due to violation or our license policy. What we need to do to resolve this problem?

Since yesterday I’ve this problem too. I also can confirm that I’ve only one client installation on my Desktop.

Hello Stanislav,
this error is generated when you have been banned for the commercial use of eM Client’s FREE license.
If you wish to resolve this you need to contact sales@emclient.com
