Why won't eM let me get past the trial version?

I have the trial version of eM, and am getting a pop up window to either download the free or paid version. Both links lead to an error message. So I have no way to get past this, and looks like eM will deactivate in 1 day if I don’t do something…

Link for getting licence is http://www.emclient.com/pricing

Thanks Milos, I tried that link, but it says that my email address already has a license so licensing failed. And yet I get a pop up window telling me to register or lose my eM client. Not sure how to resolve.

Hi, If you have your licence key,do the following:
Deactivate your licence - Click on Help > License, press Deactivate.
Now add you key and active it.
Thanks
