Belladonna

I was just over at Belladonna's site to see if she had trailers up there and I noticed on the side of the page, that it mentions a free trial offer. I like Belladonna's work, but her website is one I have never joined so I thought, hey, that's a great deal, why not. The problem though is it brings up a page which asks you to enter a name and password and to agree to the trial terms - all standard and reasonable. On top of the page is a graphic which looks like a lottery ticket and it says scratch for code. It seems to be a .jpg image or maybe I'm too stupid to realize how you are supposed to scratch the image. Anyway, just typing in my choice of usernames and codes only brings back invalid messages and says that something I entered was wrong or that that username was unavailable. I've tried many different ones. Can someone help me figure out what I'm doing incorrectly? Thank you.
