Norton Internet sercurity for 3 PC's

"Activation incomplète" - "Attention requise" - "Norton Internet Security a rencontré une erreur.  Erreur 8505, 129".

(the program works in French on my desktop)

Windows XP

Please what can be wrong?  I had a small problem during a hard disk control this evening.  It finished the first of the three steps but then the second step was only completed for 1% and it didn't continue.  I reinstalled windows and Norton Internet security also.  Maybe it's just the consequence of closing down quite suddenly.  

Additional question: what do I have to do with the "code de déverrouillage d'activation"

Thanks.
