If despite having activated Sigmund once, a splash window still keeps saying you're
using an unactivated version and asks for a license key file
every time the plugin is loaded in your host application, you
may activate it manually by copying the license key file (Sigmund.d16key) to the proper
location on your hard drive:
On PC (Windows 7, Windows Vista):
\Users\[your_user_name]\AppData\Roaming\D16 Group\Sigmund\
On PC (Windows XP):
\Documents and Settings\[your_user_name]\Application Data\D16 Group\Sigmund
On Mac:
~/Library/Application Support/D16 Group/Sigmund/"
First make sure the location exists. If not please create manually required folders.
'~' means your user's home directory. Very often "/Library" folder in
user's home directory is hidden and you won't see it normally in Finder.
If so, please select the Go menu in Finder and choose Go to Folder...
option. Type "~/Library" in the window and Finder will open this
hidden directory. Then just, browse to Application Support continue on down the tree.
This refers to the name you use to log in to your system; so, when looking for a path on Windows, just replace [your_user_name] with the name of your system user.
