Report Magic generates reports with Analog running against the log files in from your web server. These log files are pointed to by the Analog config file or command-line options. Under common use, this process is scheduled to run nightly and Analog may read all logs in the folder for the web server or may select logs to read based on command-line parameters (often chosen by date).
Given that your stats ran back through 2007 and are now empty, I would guess that your configuration is set up to analyze all access logs that your web server has generated and that your hosting company decided to move, rename or delete these logs to save space. You should look at the configuration file settings for Analog to see where it is looking for logs and should check with your hosting company on the status of the old log files.
