Althea Northman

First, apologies for my lack of knowledge. I need help with a demo. It is a demo for a body/skin, from 7deadly skins. I applied the body/skin - actually, I only applied the gold cube, not the little skin looking thing. It will not come off! I have taken off my body, etc - I use slink - and put it all back on - TWICE. The demo is still there from the neck to the ankles. It is not on my feet, hands or head. I have tried to get a help from the store, 2 days and nothing yet. I am a little desperate! Please help if you can! Thank you in advance
