Problem
Your DCS setup is running behind a proxy and reputation lookups are not being completed.
Solution
The reputation data relies on the shasta data and not LiveUpdate. Lots of users have DCS set to run behind a proxy which prevents direct access to the Internet. At this point in time you cannot specify proxy settings for reputation lookups in DCS. By being setup behind a proxy this aspect of DCS does not function. At this point in time there is no direct solution to your problem.
