Titolo: Aiuto urgente

Salve ho un urgente bisogno d'aiuto.
Sono stato costretto a disinstallare netbeans 3.6 ed a reinstallarlo. Ora se 
provo a compilare classi che funzionava e che venivano compilare senza 
problemi prima della disinstallazione mi viene ritornato sempre questo 
errore:
museo/Stanza.java [21:25] cannot access java.io.Serializable
file java\io\Serializable.class not found
1 error
Errors compiling Stanza.
Che significa? come posso risolverlo?
Grazie.

compilare classi nel package java.awt e simili:
