Hello,
A staff member has replied to your question:
Hello Ma,
In order to investigate this issue,we must verify your ownership of the software and associated Steam Account(s).
If you purchased software through Steam with a credit card,please confirm the card type (Visa,Mastercard,Discover,American Express),full name,and last four digits of the card used with the order(s).
If you purchased software through Steam through PayPal,please provide the PayPal account holder billing information (name and address) and the PayPal Invoice ID.The Invoice ID will be 16-18 digits long and comprised of only numbers.It may be listed as the Order Description Number.
If you registered software purchased at a retail location,please handwrite your Support Ticket Number ****-****-**** directly on the quick reference card or sticker above the CD Key (the number should not be written on a separate piece of paper or inserted with an image editor) and reply with a digital photo or scan of the CD Key in .jpg format.Please ensure that you submit a full-color image,rather than a photocopy

为了调查这个问题,我们必须认证你所使用的软件所有权和相关的steam账号.
1.如果你是使用行用卡通过steam购买的软件,请核实你的卡的类型（ visa,mastercard,discoverd）,你的名字,和卡上最后四位数字.
2.如果你是使用paypai 购买的话.请提供paypal的账号,地址,ID （ 16位数字）.
3.如果是在零售商处购买,请提供你支持的票号和CD 号,用数字照片或 jpg 回复.请注意要彩色照,不要复印的.
