Expired Free licence

eMC has been counting down, to end of a trial period? But I have been using it for several years now it says I cannot send mail.
If I go to licence, it tells me I already have a free licence.
If I request an activation code, it says one has been sent but nothing arrives.
This is the only machine where I use eMC, The previous therd on this is 7 years old so posting new one

Problem solved, reported to EMC and received an activation key, no explanation, by its working again so that’s fine
