NIS 2010 will not update anymore

I have had norton products for close to 20 years.  Thanks for the service.

currently I have NIS ver 17.8.0.5 and It tells to to FIX it starts to update with 60- 80 mb of needed update and invariably quits. I have Win XP.  I saw a thread with Carlos Linares that discribed killing some .x files in the lue file.  I cannont update and I have over 2 months left on my subscription.  Thanks.
