There is no such thing as " Wiccan powers ". Wicca is a religion, not some group of super-heroes. Anyone can become Wiccan should they choose to follow the particular beliefs and practices of the religion. So no one is going to be able to help you "unlock" something which does not exist.
You might want to take a look at the thread " What Wicca Is and Isn't ". http://www.spellsofmagic.com/read_post.html?post=637268 That might help you to understand Wicca better.
