When attempting to download files from the Motion Library on Windows, you may receive the following error message: I/O error when communicating with DNASTAR Motion Library Server. This issue may occur if Windows Firewall is On and Outbound Connections are Blocked. Simply adding Protean 3D to the list of allowed programs is not likely to correct the issue. There are several possible work-arounds:

  • Download the entire Motion Library from our website.
  • Add one of these rules to the Windows Firewall Advanced Settings dialog, which is accessed through the Windows Control Panel’s “Security Settings”:
  • Allow Protean 3D to make outbound HTTP connections.
  • Allow Protean 3D to pass through the Firewall on port 80.

For more information on creating rules, consult Microsoft’s support page for Windows Firewall Advanced Settings.
