Authentication required for manual

I have Audacity 2.1.2 installed on Windows XP (I know, I’m very ancient). I do not remember when I originally downloaded it if it required a password to do so.

Anyway, every time I click on a link for the help file there is a box that pops up “Authentication Required” I can close the box and continue reading the help article. But I would like for the box to stop popping up. How do I fix that?

Also, I have another account on this forum under a slightly different username “Teduardo”, but I had not used it in years. When I tried to log into it I either the password was no good or I don’t know. So could someone please delete that account cuz I’m not not using it and there’s probably nothing in it.
