Free License Invalid after computer upgrade

I replaced my motherboard on Saturday and now emClient is saying my license (free) is not valid. How do I fix this without messing up my mail?

I found it in this forum: go to http://www.emclient.com/lost-activation-key?_ga=1.249767054.964991353.1462458062

Works now. Thanks.
