I have one e mail account and use em client on my desktop & laptop. I bought a new laptop & installed em client and entered my free license and it worked. This morning I went to my destop computer and it tell me license invalid. Both worked previously. New laptop ok but not my desktop?
The license is restricted to a single installation of eM Client. If you want to use it on more than one computer, register a second Free License using a different email address.
Otherwise you need to deactivate it on one computer before you activate it on another.
