I'd suggest making sure you're using notepad as it doesn't introduce any funky EOL characters that could be messing up the format (thus keeping the dataserver from properly reading the file).
I'm wondering if you're updating the correct file ...the log should print out a message stating the full path of the *cfg file it's using (ie, are you editing the correct file?).
Is the *log still showing the same number of pages (ie, '3398304'), or is it showing a new/larger number?
