Alienware windows 7 problem

I just bought an alienware computer and MyColors was already intalled.

When I first turned on my computer, there was already an alienware theme applied (name of the theme : BREED).

I noticed the stardock MyColors program and I opened it (not knowing what it was for) and saw my active theme and the "restore windows 7 theme" button.

I clicked on that button and everything went back to windows 7 normally.

I left it like this for a couple of weeks and then I felt like I could go back to the alienware theme.

THIS IS WHERE MY PROBLEM STARTS.

I can't go back to the alienware default theme. It's not appearing in the Stardock MyColors' menu.

I know where the files of my alienware theme are, but the program acts as if they don't exist.

Now, I've never bought the program or the theme and I don't know how to restore it.

Please help.
