"Neon lights karaoke song lyrics"- graphics not working

Hi, I downloaded the lisence for this effect from adobe stock, and have been working on a video using it for a few weeks. I've always saved my work before closing, but today when I continued editing, the background (which i s supposed to be and used to be a brick wall) is gone, and there is this instead. How do I fix it back? I've tried adding the texts all over again but the same keeps happening.
