I would love to see if I can help you out first-hand using something like teamviewer.
We've been through a number of different server providers and lived through a ton of TF2 updates.
We have identified the stats configuration file for the domain under evaluation.
For the purpose of anonymity I am using “domain.com” here, it should be replaced with the actual domain name being investigated.
I haven't had the chance to use the hlstats offering by NFO(I use my own installation), do you have daemon logs that you can look at?
