Yes - It is most likely the Dep problem if you get no data with the sample site profiles. Try the following:

Go to Settings - Control Panel - System - Advanced tab - click Settings button (under Performance) - Data Execution Prevention tab.
Select the 2nd option (Turn on DEP for all programs...) and in the exception list add

a) surffox8400.exe (located in c:\Program Files\SurfStats<Version>) if you are using SurfStats Website Traffic Analyzer V8.4 or later or
b) surffoxlive3400.exe (located in c:\Program Files\SurfStatsLive<Version>) if you are using SurfStatsLive 3.4 or later.

Request the report again. You must add surfschedrun.exe to the DEP list as well if you use the scheduler.

No - Check the following if you get reports with the sample site profiles:

• That you have specified the log file name/s and path correctly, e.g. D:\Data\Logfiles\*.log. A common problem is that the file extension is not specified.
• That the program has rights to access the log files. Check that the SurfStats Scheduler has start up administrative rights to the path if the log files are hosted on a remote drive: Control Panel - Administrative Tools - Services - right click on SurfStats Scheduler.
• That the log file has valid data.
• That the required fields are logged in the log files.
• That there are no filters set that exclude all the data.
• That the firewall is not blocking access to the log files or to the report destination.
• Make sure that you do not install the program over an existing version. You must uninstall the program first, then delete the surfstats directory before installing the program.
