Just trying to figure my way around this. I have recently updated all the software hoping to get a more reliable delivery of content. Seemingly the opposite has happened. I am now unable to publish content to the screens and see the above message in the Log files. I have tried a number of fixes that people have outlined on here but to no avail. Before last week I had the software working on my Server 2008 R2 box.
