If yo bouht it from Amazon you have 7 days to return it. Try going to
http://www.amazon.com/gp/css/returns/homepage.html and plugging in the information and see if they can take it back. I mistakenly ordered some goofy book by clicking around on a stalled browser pages, when it UNstalled all my mouse clicks pured through and lo and behold I bought a romance book. Not my cup of tes. I emailed Amazon and in an hour or so had a refund.
Just don't abuse the priviledge and they will take 'em back.
