Edit: I realize 2016 is too early for netfile. I'll settle on mailing.

Hello, I'm attempting to file taxes for a couple years ago, specifically 2016, and I'm getting an error message saying "File Rejected" with no specific guidance/warning on where the issue is. I'm wondering if this is because I'm attempting to file for something multiple years back, or if my change in address since then is posing problems? Please help.
