Same thing happened to me. I have reinstalled Windows once or twice since the last time I ran Emsi trial, but it still said my trial was expired. Weird.How does EAM check out the licence? I wanted to try out something, but it says, that the trial has expired. I have never installed EAM on this setup before and I have clean installed Windows on 14-Nov-17, obviously less than 30 days ago. I guess, that disabled Windows Event Log might have something to do with that.
