Hello grumpierer,

Like the name....

Can you confirm that the password worked before you upgraded?  It should still work.  Don't forget it is case sensitive i.e. it sees upper and lower case letters as being different.

If you had previously set a password, did you set up any buddies?  If it has locked then you could get a buddy to unlock it.

If it is not locked you could try un-installing, then reinstall and set a new password.  Having bought the full version the password/code you have used should still work on the new installation provided it is the same phone.

Other than that you will probably need to wait for a Norton employee.  But hopefully you won't.

Good luck.
