Required help in unlocking samsung note after inatallation of norton mobile security

dear friends,

i am facing problem in unlocking the mobile samsung note GT-N7000 after installation of Free 90-day Subscription of Norton Mobile Security. The message shows that Device locked because SIM card is missing.

I tried my passowrd but it is of no use.

Also i tried sending sms "unlock" and "unlock --buddy mobile no" from both buddy but it is of no use.

now what i have to do , i can take the risk of erasing / formatting the mobile  i have also sent"report a problem" but it is jst waste of time.

plz help so that i can use newly bought note.

i installed the norton mobile security on 9th march 2012.
