AboutScreen.java

Buenas! sou novo na área de programação, e me deparei com um problema de um script pronto, mas não sei nem por onde começar, então se alguém poder me ajudar, ficaria grato...

OBS.: Esse é o script original e está funcionando corretamente.

Apenas foi removido as seguintes linhas:

append("- View the Pork  camp and return back to");
        append("Angry  by  Arkantoz S60 screen back and");
        append("forth.");
        append();
        append(" Angry Birds!");
        append();

        append();
        append("                                Arkantoz ");
        append();
        append("                               Version 2.0");

E não compila... se eu modifica com o Cavaj da erro na hora de executar o jogo e com o NetBeans nem chega a compilar, tentei também compilar com o javac pelo Prompt, da erro...
