What must the config file include?
This file contains the path necessary for the program to reach the database. You can read more about its editing options at "Can I change the default path of the database file?" title. Its structure is simple, however it can happen that the content of the file is damaged or it is not properly saved after editing because decoding of the file is changed unwittingly (in case of a special path UTF8 character coding has to be used).
The file can be downloaded from here, but in this case its content has to be edited (everyone knows where is his own database). You can read more about this at the title mentioned above.DOWNLOAD
