License keeps disappearing

I’ve had a free license in place since 2015 and, over the past week, when I go into the program it asks me to input my license. I put my original original license information in and it works fine for the day but the same things happens again the next day.

This has never happened before so not sure if its a bug?

Thanks.

You’re not using the same license on more than one computer, are you Jon?

What version of eM Client are you using?

Ah. Thanks Gary - that may well be it. I replaced my computer and think I’ve put the same one in that I have had on the other device all these years. 

Will put the other licence in and suspect that will sort it.
