Microsoft has confirmed to Gamasutra reports that users are having problems browsing and purchasing content from its Xbox Live and Games for Windows Marketplaces, saying an "internal operational error" is behind the issues.
Online gameplay and other features of Xbox Live appear unaffected by the problem, which was first reported by many gamers earlier this morning. Microsoft says it is "actively working to resolve the issue as quickly as possible," but gave no word on when service is expected to be restored.
