Er code -42003. I am trying to download this part of a cd and keeps stopping with

[gathart]

code. Every time when i visit the itunes store three requests of my id pops up, followed by an attempted download (its a part of ''Plastic Beach'') then it stopped quoting Err = -42003.

Has anyone ever come across this problem and if so, how can i solve this problem?

Many thanks for your help,

Gerard
