Error during Media/Metadata Update and now Startup

[Edward Mallett]

I set my Launchbox to update all media/metadata and only add to items missing metadata. I walked away and when I came back Launchbox had an error and closed itself out. Now, whenever I attempt to start Launchbox I receive the following error:

Value cannot be null. (Parameter 'key')

I enabled debug logging and attempted to start up Launchbox again. I have attached the most recent log.

Close LaunchBox, then navigate to \\LaunchBox\Data\ImageQueue.xml and delete the file there. Then re-open LaunchBox. You will need to start up your media downloads again manually after that but should be able to at least get in app. Leaving ticket open so I can attempt to track down the initial cause of this error.

Done and thank you. Let me know if you need any additional information.
