Anubis Help?

Like a bunch of others in the simming community, I'm a custom content fanatic lol. Anubis Under The Sun has such AMAZING(!!!!!) custom items, but I can't seem to download them properly to get them to work in my game :/ I followed the instructions on Mod The Sims, and other content works in my game. Does anyone have any suggestions?

if it's old Peggy children and toddler hairs, there's nothing i'm aware of. They went a little glitchy with the first pets patch and i'm not sure if they ever got fixed.

If that's not the case, what exactly is it that you are doing?

well, i save it to the packages folder because it's already a .rar file and not in a folder (.zip) that i can extract. I've done that with mods and other custom content and it's worked fine. I don't know why this is giving me trouble :/
