LIGHTSQUID NOT UPDATING REPORTS

[chris.pearce]

HI,
Our company is using PFsense with lightsquid and Sophos to monitor internet traffic,
However the Lightsquid reports are not updating it is missing 4 days worth of data and some users are disappearing:
Settings are:
reportscheme novaSea
IP Resolve method is on demo
refresh rate two hours
does not skip urls.

any help would be much appreciated, I have limited experience with PFsense and require really as much help as possible
