Imdb.com composers credits...?

My name is Andrew J. Rausch. I'm a film writer/producer who records hip-hop music under the name Tekneek. My song "Blow Up Sh*t!" appears in this film. I was credited on Imdb.com as a composer for my song, but now my credit has disappeared. Does anyone know why/how this happened? I mean, I'm the guy who added this title to Imdb.com in the first place!? If anyone knows, feel free to email me at [email protected]. Thanks! --Andy
