OK, so I downloaded all 3 sets and the LackeyCCG from the website into a folder on my desktop. I have all 4 of those zip files on the main part, as well as an unzipped LackeyCCGWin. Within the Lackey folder there is another folder listed LackeyCCG & _MacOSX. Within the Lackey folder I have a plugin folder, within that folder I created a Redemption folder, in there I have the zipped Redemption folder as well as the unzipped one. I also deleted the "Packs" folder and then created a new one with the unzipped update 1.2.1 folder.
What did I mess up? Lackey shows the Redemption folder but won't let me open it. I'm not use to this kind of stuff, so there is no telling where everything went wrong!
