I have tried everything I can think of to fix this problem. Is the Community Applications Down?
Download of appfeed failed. Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of8.8.8.8 and 8.8.4.4 and try again.
Alternatively, there is also a chance that the server handling the application feed is temporarily down. Switching CA to operate in Legacy Mode might temporarily allow you to still utilize CA. It *appears* that a partial download of the application feed happened (or is malformed), therefore it is probable that the application feed is temporarily down. Switch to Legacy Mode, or try again later)
