Title licensing change, corrupted video file, sad times

I've seen other posts about this, but it appears Rush had changed how to utilize title graphics and I can't get any of them to work. This is problematic in that I've been creating education videos for my thesis and everything has been streamlined with matching title overlays up to this point. 

I tried to work around this initial issue by redownloading a previous version of Rush (using apkmirror). However, I don't think it did anything, so I redownloaded Rush through Google Play and logged in and all of my projects are unworkable. Each clip (audio, video, and picture) is red with an exclamation point. 

Two things: Can I get these projects to work again? And when I do, how can I use the same titles I've been? I tried advice from other posts about this and it messed everything up. I'm using a Google Pixel 4 to work on these projects, but even getting onto my Acer laptop they were all red.
