If upgrading MDaemon from a version prior to 14.0.0, the Standard theme will still be availble to use in WorldClient.
If installing a new instance of MDaemon or rebuilding the WorldClient directory with a 14.x installer, the Standard theme will not be included.
The Standard Theme can be downloaded here;
http://files.altn.com/MDaemon/release/worldclientstandardtheme14.0.0.zip
Download the file and unzip to the \MDaemon\WorldClient\ directory. Restart WorldClient to load the profile.
