After plenty of experimenting I managed to find what the cause was.
It seems that at some point I installed the jukebox using a non-default filepath and then uninstalled it.
This time when I installed it, I used the default path. All of the registry entries for 'imag*.dll' where still pointing to the original install location. These entries must not be deleted on uninstall or altered on a reinstall to another location.
When I changed all entries in the registry that were pointing to the old location to where it was now installed, it worked!!
