Hi ukvibes,
That message would not affect your listing here with us in our directories. As explained above that is just related to the shoutcast.com directory.
With the track title info that is missing, is this when using the AutoDJ? If so, then you will want to check that your uploaded files have the correct meta-data embedded in them.
Which encoder software do you use for your live streams? When a live source is connected the website information is taken from your encoders settings, not the Centovacast control panel settings as that is for when using the AutoDJ feature.
