As a recent Smartertools user, I'm still getting to know my way around.
We installed SmarterStats Professional Edition 3.3.2761 running under Win2003server, IIS6, etc. and a couple of the sections report no data:
Search engines: "Search Engine Breakdown returned no data for the date range"
Referrals: "1 No Referrer (bookmark or direct-entry)
Everything else seems to report correctly. Any ideas where to look would be helpful.
