If IDA won't download any file (errors 10049, 10057, 10060...), there may be one of the following causes:

no connection. Check if there is access to the Internet from other programs, for example from your browser;
access to the Internet is blocked by firewall or, sometimes, anti-virus. In this case you have to adjust your firewall settings so that IDA has permission to access the Internet, or check if your anti-virus settings allow programs on your computer to access the network (for example, network access is sometimes blocked when the safest settings are enabled in anti-virus software);
proxy-server is not specified. Check proxy-server settings in IDA -> Options -> Proxy settings. You can try to disable "Use proxy-server settings from MS Internet Explorer" option if it is enabled;
proxy-server specified incorrectly. Check proxy-server settings in IDA -> Options -> Proxy settings;

Sometimes trojan programs set invalid proxy in the IE settings and IDA uses those settings (if "Use proxy-server settings from MS Internet Explorer" option is enabled).

If IDA won't download some particular file only (errors 10049, 10057, 10060...) there may one of the following causes:

no connection to the specified server. Try to download later;
invalid proxy-server or proxy-server is temporarily unavailable. Check proxy-server settings for this download (Download properties) or for the server (Site manager);
probably specified incorrect download address(URL). Check the download link.
