I lost all the content in one of my boards.

One of my boards: Media Workflow: Planning, has lost all of its content. Another board with the same name is there, but it doesn't have my background photo, nor does it contain the correct content. This is a very stressful and inconvenient loss. The board is not under closed boards. I need to recover this content. I don't think I can replicate this board correctly from memory and it is a critical part of my workflow as it contains links to all my work, resources, and a log of all the steps I have taken on each project. I feel sick. Please help.
