cubase le5 activation

Hello folks! Italy here.
I’ve just bought aLexicon Alpha Desktop Recording Studio with the DVD Cubase LE5 included.
I’ve installed Cubase but, in the activation online, the serial number provided by Lexicon (BBDOX-AAXWS-HYBFR-NEIYA-ANBEA) doesn’t work (online the message is ‘the number doesn’t exist’.
Which is the problem?
What can I do?

Thanks a lot
