As the title says, that is the error I am getting. It pinpoints this error at line 2 of the following code for my very basic class:

```auto
package {    
    import flash.display.MovieClip;
    public class Block extends MovieClip{
        public function Block() {
            // constructor code
        }
    }
}

```

If you need more info, lemme know.
