reshade failed

hi there, ive been trying to install reshade 3.0 for the past 3 days. the one time it got into game the shadows from the presets were missing. then i uninstalled it and now it says unable to download archive?? ugh im really bad at this computer stuff.

It would really help with more info like what game you're trying to add it to and what preset you're using and from where (incase of non standard shaders)
