The report about a problem which some user can't install the game.

Thank you for always playing TITANSLAYER II. In response to your inquiry that ""the game can not be played properly"", I confirmed this issue with Valve's steam team. It turned out that it was a problem that occurred when using Beta version keys distributed for media before the release. These keys become unusable after the release. Please purchase released version of TITANSLAYER II from Steam. In addition, we will issue the latest key once again only for users who have inquired directly to us via email and received the Beta key. Sorry for your inconvenience but please contact us with the e-mail address you used to contact us before. I am sorry for troubling you. Thank you for your understanding.
