As mentioned, I contacted Rizz before, but he couldn't get my pack working. The devs are probably busy with the translations right now anyways, so if I do decide to ask Rizz, it'll probably be after 1.20.
As for my skin pack, if you don't know how to install the other skin packs properly, then unfortunately it will be even harder to install mine, since (with the greatest respect to the other skin packs) its actually more complicated as it includes minor attrib modifications for things like the Tiger and Pershing commander. Finally, my skin pack is private because it includes some modified work of other skinners, and under ethical principles I can't mass release it. If you really still want my skin pack as opposed to the other already released ones, you can PM me.
And yea the Relic skins SUCK hard. Snowman uniforms for the grenadiers are my biggest personal pet peeve. Feldgrey coats FTW!
