On Thursday WorthPlaying broke the story of US players finding that their downloaded Resident Evil 5 demos were mysteriously corrupting as soon as they logged in to Xbox Live. Capcom provided a statement in the original story and Microsoft has also provided us with an update.
"Earlier this week a demo of 'Biohazard 5', known in the US as 'Resident Evil 5', was released on Xbox LIVE in Japan. While the content was only intended for download in that country, a number of gamers outside of Japan were able to access this demo for a period of time. By putting measures in place to ensure it could only be downloaded in Japan the demo version was effectively reset, meaning that it is only supported by LIVE in the correct region. We look forward to being able to offer our gamers a chance to experience a US demo of this eagerly anticipated title soon.
