Upgraded desktop computer and now I can't receive my emails

I been using eM Client on my laptop and old desktop computer.  I upgraded my desktop last month. Today I open up program and it tells me I need a license.  WTF!!!  I’m not using the other desktop. Why can’t you just remove that desktop and authorize my new one.  I’m on my desktop more and would like to receive my emails there.

Did you just try to put your old license code in?  If you don’t know it, got to http://www.emclient.com/lost-activation-key and enter the email address associated with your eM Client license.  They will email the key to you (you may need to user your web-based email program to get it).
