This document contains some of the issues that may be faced after upgrading to the Enterprise version of Content Player and Content Manager Desktop.

Content Player

A Digital Sign is Not Displaying Newly Deployed Content

Problem:  Changes have been made in Content Manager and deployed, however they are not appearing on a sign. Opening the configuration window shows an error when pressing Check for Update or Refresh.
Cause: Signs running Content Player versions 5.12 and below no longer connect to the deployment server due to security changes FourWinds implemented in version 5.13. The service upgraded to version 5.16.2 in July 2022.
Resolution: Upgrade Content Player for Windows to 5.16.2.

Content Player does not Launch, Displays a Communications Issue

Problem: After installing Content Player, launching the application leads to a splash screen where Content Player gets stuck at Initializing service communications and does not load.

Cause: The Content Player service is stopped.

2. Contact us at and we will coordinate with you getting the password entered.


After Deploying to a Sign or Sending Commands, the Changes do not Immediately Appear

Problem: After clicking Deploy on a sign(s), the sign is not displaying the new or changed content. Also when sending a player command such as a restart, the player does not immediately receive the command.
Issue: The method used for deploying signs has changed. Rather than directly receiving deployment files via "push", signs now look for deployment changes on a set interval, or "pull".
Resolution: Please see the following KB article:


Illini Alerts are not Appearing on the Digital Sign

Problem: The digital sign did not display the most recent Illini Alert .
Issue: There are multiple issues that could cause Illini Alert to fail to display on a digital sign:

2. Each player has to be individually configured to receive emergency messaging.
3. The emergency channel subscription is failing to properly poll for a channel activation.
Resolution: The following actions should resolve the associated numbers listed under items:
1. Open Content Manager and Deploy the sign
