[SOLVED] Broken skins [noob ques.]

[Karamano]

Hey,
Got my Pi yesterday, instantly installed Xbian Alpha 3 as it is regarded the best from my impressions. Compared to its alternatives, Xbian is the fastest- indeed noticeable. Problem is for some reason skins that seem to work with Raspbmc are marked broken with Xbian. Specifically I'd like to install reFocus BIG skin. If I manually unzip it to /home/../Addons it will work. But defeats the purpose of having a repo for it.

As a complete noob who would really love to stick with Xbian, how come these are reported broken on Xbian alone? A lot of skins report broken on Xbian but work with its rivals.

Thanks.
