Just got a used Amplifire, got it connected to my relatively ancient computer, downloaded the editor. I want to restore it to factory defaults. Got an abu file in my downloads now, but can't open it. I tried an online tool but my antivirus freaked out. Is there some way to reset manually on the box? To introduce myself, I'm an old fart who wants to record better guitar sounds than I can get with my existing collection of obsolete stuff.
