It looks like the file has become corrupt. This happens sometimes.
Delete your Library folder at C:/Users/morte/Documents/ and the Config under %appdata% and restart the player. After that, reauthenticate the player and the problem should be fixed.
Due to your incorrect BaseURL, you should check out these two threads. It might be the same issue:
If you havent done yet, disable your thumbnails:
Windows automatically creates thumbnails for content in the User folder and will try to do so for the Xibo local Library.
In some cases, this interferes with the normal operation of the Player and should be disabled. This can be achieved with the following registry settings:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoThumbnailCache"=dword:00000001 "DisableThumbnailCache"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "DisableThumbnailCache"=dword:00000001 "NoThumbnailCache"=dword:00000001
