You see any data in Daily?
Just to confirm, have you tried the suggestion that
@wuckawucka made to get his system working? I don't use anything trend, so I have no QoS. I also don't use NAT acceleration (I have no need for it as my ISP is only 50 mbits.
Other than resetting the data file incase it is corrupt and checking the syslog to see if RSTATS is reporting any error (if it does - I don't remember seeing any error messages when I was looking at the source code), I don't really have anything more to suggest looking at. Sorry
