 About the Fitting Event log

The event log is a floating window which can be shown by pressing the Event Log button  in the View menu of the Fitting module. Within the Fitting module it is used for reporting errors occurring in the program during fitting exercises. It is automatically shown when an error occurs in the program. Error messages should be noted and forwarded to our support team at In most situations, such  errors are fatal and will result in the algorithm terminating.

As a first step towards resolving such a problem, Exit Dynochem, Open it again and rerun the fit.
