Cannot activate license

When I input my info to get a free license, I get this message "License issuing failed.
License for this email already exists. Only one free license per email is allowed.

You can get your existing activation key here."

When I then click on “get existing activation key here” I get “no such email found”. Please help.

Hello,
I checked it in our licensing system and discovered, that you have registered only sync2em license. Please try to get Free eM Client license here: http://www.emclient.com/free-license and let me know if it helps. In case it is not created successfully, I will create it manually in our licensing system.

Please contact me directly at: wilson@emclient.com
