Under the list of supported games when you click to the client download there are three products listed that don't include Age of Conan. When I install the client there isn't an option for it either. Am I missing something or does Curse support AOC? I see a an add-on section for it so now I'm wondering what I'm doing wrong.

As of now the only games the Curse Client supports is World of Warcraft, Warhammer Online, and Runes of Magic. But you can download and install AoC addons manually from http://aoc.curse.com/downloads/aoc-addons/default.aspx.
