I've tried to install the
Increased Texture Detail & Shine - TS3 Skin Replacements and I did like I was told, downloaded the .cfg-file, put the .package files right where they belong but I just started the game and nothing's changed.
I've made the mistake to try and open the .cfg-file with WinRAR (I've downloaded the unzipped .cfg-file without really noticing it, followed the instructions and tried to open it up with WinRAR, yeah stupid me) and now Windows recognizes .cfg-files as WinRAR files. Could that have something to do with it? If so, I have no idea how to undo that.
Maybe someone can help me out.
