So how do I solve this issue?

So just to explain the screenshot below, I wanted to try Dream Textures on a cube to see how it works but every time I tried using the add-on, I keep getting the error you see on the SS. I downloaded "sdxl-vae-fp16-fix" made by ollin, however that didn't fix it. Do I need to download something else manually? change some settings? Am I using it wrong? or my pc not supported?

My PC:

CPU: Intel Core i7

Memory: 64Gb Ram

Graphics: NVIDIA GeForce RTX 3070
