This update to exrTrader fixes licensing issues.

Changes since V1.6.1:

• changed the default location of the license file to:
  %appdata%db&wlicenses on Windows and
  ~/Library/Application Support/db&w/licenses on OSX
  to prevent issues writing the license file.Previous license files will still be used by the plugin - and the licenses from the locations mentioned above can also manually be copied into the same directory as the plugin for a self-contained installation.
