Going by the information provided, it's probably best if you just reinstall OBS Studio/StreamElements.Live from scratch, and also reinstall StreamFX. Note that StreamFX officially only supports OBS Studio, and you're on your own if you use forks.
Okay, thank you! I was assuming it might be the route I'd have to go because something in OBS is latching on to this older version of StreamFX and not updating no matter how many times I installed a newer version, I even found an old version of StreamFX.dll and it's plugin folders on another hard drive and deleted those, but no StreamFX files are on or in my Installation OBS folder and hard drive.. so that was very confusing.
I am using Stream scenes collection manager I think it's called, I'm not positive how to make sure my backups for everything keep working once I uninstall OBS but hoping they do so I don't have to redo my entire stream setup again.
It looks like I'm only using OBS Studio 64-bit running as admin, StreamElements plugin and a few others so I assume that's the correct version because I installed StreamFX before with no problems.
