Top panel roller keeps popping off garage door track

The other day the extension spring on my garage door broke, luckily I have a door that's never used so I pulled a spring off it and got everything back in working order. Except, the top left roller (from the inside, same side that the spring broke on) keeps popping off now. I've tried tweaking the alignment of the door, and the alignment of the track, but nothing stops it. Unless I stand by the door and pull down on that side while it closes, then it will close.

I've overheated my garage door opener twice mucking about with it. So I decided to see what I can find on google, which hasn't been much besides basic troubleshooting.

I'm wondering if the replacement spring has more tension, and is causing the door to bind/twist as it goes down. However the spring is identical to the old one so, I'm also wondering if maybe the rollers are just worn and I need to replace those. This door has been in use for years and as far as I know, they've never been replaced.

Hopefully someone with a bit of experience will see this and point me in the right way while I'm googling.
