To check if your license is activated, click the main “WF” icon in the top left corner of the application window, then click on Online Registration.
The details there will tell you if the application is in the demo mode or if a trial[1] or a full (paid) license is activated. If it is activated, the information will also tell you how many days you have left before your license expires.
If you own a license and want to activate it, see the article on how to license Wordfast Pro.
