Query: Disaster / waste of money

On my Dell XP system, I was never able to install NAV2005, it hung. After a 45 min wait, I spent 3 hrs with Symantec tech support, but still not able to install. I'm out $50 and the computer has lost some functionality, e.g. the search engine has lost ability to search by date, file size, etc.
