Yes of course, we can change you over to a Shoutcast v2 server instead. Please be aware though that for this we will need to delete your current account and then manually recreate this as it is not possible to change a server accounts type once it has been created. We will be able to keep all of the settings the same for you but you will be assigned a new port number. So you would need to resubmit your station again to any directories that you may be listed with.
So as long as you are ok with this, then please let us know a good time for us to do this as it will mean a small amount of downtime but no more than about 10 minutes as you do not have any AutoDJ files to be backed up.
We do think this would be better for you long term as you will be able to block any IP's yourself from within the Shoutcast admin page.
