Issue with older Norton product

I have a client running NAV 2002 (yeah I know) on an older computer that can't really handle anything newer.  Believe it or not, the definitions have been working until this week (probably around 5/11).  After that, the updates cause autoprotect to crash at startup.  Obviously I know it's not supported, but just wondering if anyone out there is using an old version like this and having this problem...
