I was able to update via -update_experimental.bat- now, a few days ago this wasn't posible, when u try to start after installation, on the console it will appear an error, ("tuple index out of range") and ask u if u want to (re)install the models, just type n for cancel that, it will open the page, however, there's a little "bug" with the token "thing" i think, u have to load a ckpt using model manager, then click on update model, that solve the issue, then change the sampler option, lets say ur using dpm++ sde karras, change for whatever option, generate an image and then go back to the one you use, if not the image will be generate really bad xD, sorry if this are broken english, isn't my main languaje :3
