I have changed the password associated with the email address at which I received the "warning." I don't know if it's too late.
The originating email address of the warning was "support@seriflabs.com," which, at least according to Verizon, doesn't exist.
BUT I DID NOT CLICK ON THE RADIO BUTTON IN THE EMAIL. I WENT TO THE FORUMS THE OLD-FASHIONED WAY, TYPED IN MY USER-NAME, "AMERICAN," CLICKED ON THE AUTO-FILL (CORRECT) PASSWORD--AND SAW THAT THE ACCOUNT WAS LOCKED. AFTER THREE TRIES, I WAS LOCKED OUT FOR 15 MINUTES. WHAT WAS WORSE, WHEN I CREATED A NEW PASSWORD, MY REAL FIRST NAME WAS GENERATED AS THE FORUM PROFILE NAME. Look, for the past thirteen years, private talk among me and some other Serif users at times addressed our mutual perplexity that Adobe never sued Serif for at least the appearance of appropriating a huge swath of its software. One of my forum friends postulated that Serif might be related to our two governments. What did I care? I know they're into all my stuff anyway, so devil take the hindmost, I figured.
But I did NOT click on any link. And my "American" account WAS locked out. And my first name did NOT appear on the "American" profile. Sweet Jesus, i just would appreciate someone telling me what the heck might be going on.
I CANNOT CHANGE THE PASSWORD TO "AMERICAN" BECAUSE SOMEONE HAS ALTERED IT. I NO LONGER HAVE ACCESS TO THE ACCOUNT.
Thank you.
