5090 comfyui

Currently running a 5090 with Ryzen 9 and 128 gb of vram. This was my first build and I know it was ambitious after I got it built, I was amazed she turned on the first time. I immediately optimized my graphics card and also got windows up and running. All of my hardware is up to date. I then went and downloaded comfyui made a couple history videos. Ran into the manager problem the not being able to download problems. I went in circles for the past three days. Even went the Blackwell route downloaded 7bit to use but it wouldn’t allow me to use 7bit to unload the Blackwell files they made. Does anyone have any suggestions or help for this? Much appreciated ive spent way to much money on this thing with the dream of pushing ai content to the world. Please let me know. Thanks in advance.
