Tito

I activated ESET, but when I got windows 10 I had to re-download everything including ESET. When I downloaded it again, I tried to activate it with my username and password, but I tried everything, and I can't remember my password &/or username. I went to License Management Support, and entered my email, I got and email giving me a new username and password, but it expires. Is there anyway for me to retrieve my username and password, and not get an expiration date?
