The trace log is a file designed to allow support personnel to diagnose problems.
If you change the enable trace log setting to Yes, Ripplestone will begin to generate a log every time someone signs onto Ripplestone. The log files are simple text files that get written to the "Data" subdirectory of Ripplestone (the default locations is: C:\Program Files\Ripplestone\Data). The log files will include a history of each of the significant steps that Ripplestone tried to execute. The logs will tell you exactly at which point an error message may have been generated.
The log files are called "Ripplestone UserID". There will be a separate log file for each user who signs onto Ripplestone. Set enable trace log to no after you are finished diagnosing a problem.
