Just bought and registered Star Hammer: The Vanguard Prophecy.
Installed it, entered serial at protection screen (with and without dashes) -> "Proceed" is greyed out. Only cancel worked. Copy/Paste, entering it one by one, installing the patch... no chance. Cannot play game. Great copy protection!
ok, it happens, faulty S/N or extra bits can be added by copy paste and manual typing, but to be sure, just send a message to support as see, as they can at least check the S/N for you, where as i can't i'm sorry to say
