Hi Richard,
the resolution of the screenshot is unfortunately too low and I can't read any text on it. It is strange that your shortcut says 5.03. Maybe you are running two different CPT versions? CPT is not creating any shortcut automatically so I guess you've created the shortcut yourself. Maybe it needs to be updated manually.
Usually CPT de-installs previous versions before it installs a newer version. Please check if two different versions do exist though. Also, check where exactly the shortcut is pointing to.
You say that you are running the CPT Pro version. As I can't read the window title of CPT on the screenshot I want to double check with you that it indeed says pro version in the windows title. Only the pro version supports different skins.
Last thing: please check in which folder the layouts are stored right now. It should be "Documents\Chess Position Trainer". In the past CPT would store it in "Documents\Chess Position Trainer 4". Does CPT update the layout files in the folder? Please check the file dates after closing CPT. Does the date and time match your current time?
Thanks,
Stefan
