Hello Artem, Your account has been tied to another Steam account. In order to investigate this issue, please provide one of the proof of purchase below for a game registered to each of these accounts. Without proof of purchase for this account and the other account in question, we will not be able to release this account to you. If you purchased software through Steam with a credit card, please confirm the card type (Visa, Mastercard, Discover, American Express), full name, expiration date, 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 4**2-ZM*O-7302 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. If you have any difficulty locating the CD Key on the packaging, please see the following link: URL: http://support.steampowered.com/kb_article.php?ref=7480-WUSF-3601 Example scans: http://support.steampowered.com/images/faq/2347-QDFN-4366/cdkey1.jpg http://support.steampowered.com/images/faq/2347-QDFN-4366/cdkey2.jpg After verifying your proof of ownership we will gladly assist you with this issue.
