Install application skin

Hi Guys,

I had converted and signed an application (UBerMusic) on my playbook and success side loaded it

google play link
https://play.google.com/store/apps/d...udio.ubermusic

and
.BAR link
http://users.skynet.be/am034905/UberMusic_1.0.1.bar

But
Actually, i cannot install the Metro Skin (like WinPhone7 skin) to enjoy 100% that app
Google play link
https://play.google.com/store/apps/d...Ryb3NraW4iXQ..

The skin is not a app so how can i install it?

Thx

Some extra functionalities of apps may not work due to RIM blocking their access to core PlayBook APIs. I'm not 100% sure, but this could be one of the reasons it doesn't work.
