I got a new computer and I went to redownload paint.net and the plugins I had. When I click on the download to BoltBait plugin pack or pyrochild plugin pack it says, "Your connection is not private". I don't know what to do, I've tried cleaning my SSL, I turned off my anti-virus and tried to download it and it still says "Your connection is not private". I've been using Paint.net for years with the same anti-virus too and this is now happening, What do I do?
