Live Update problem

When I run Live Update, it downloads everything except Virus Definitions part 2 of 2, then I get error message

LU 1835 or LU 1865.

I have an older version:

         Internet Security 8.3.05

         Virus  11.15.11.1.

I went to the download section and these versions are not listed.

When I ran their auto detect program for the proper download it could find no Norton program on my computer.

Is this a subtle way of telling me my version is no longer supported?

Any help or info with this problem would be greatly appreciated.

Thank you
