Shoutcast job

I have a shoutcast station & i receive the following message: WARNING: You have exceeded your available hosting space limit!. You may delete some MP3 files by using playlist manager. If you have already exceeded your space limit before WHMSonic v2.1 version, "Please Click Here" to delete/terminate your current AutoDJ and all MP3 files under your account. There is a new upload feature + new AutoDJ is available, you can upload mp3 files by using your browser under the playlist manager. FTP features have been disabled. I click to delete files, but my account is still showing I have exceeded space and the radio is no longer working. I need someone who knows Shoutcast & WHMSONIC control panel really well
