If you haven't used it for a while, there is a recent update that includes extra features. I suggest that you log in to your account via the jukeblaster.com website, download the videobox that is in your download folder and install it.
You will need to remove the old videobox from your machine first, but do not remove your music files, and keep your licence file on your desktop, so that you can add it straight back in to the folder when the new install is complete.
The new features are quite good, so make full use of them, we bothered Steve and Bry for them for quite some time, and they finally gave in.
Hope this helps.
