I am using PhPED version 4.6.1 (build: 4627 ). It worked for a few days but now the IDE doesn’t allows to save or execute any command from the top menu. (e.g run, search) . It doesn’t respond at all when I press on those menu options.
Dockable windows however work (they fold and unfold and I can change properties of directories in workspace window).

To make it work again, I have to close the IDE . While doing so, it does ask me if I want to save the unsaved file and works accordingly before shutting down gracefully. The next time I open it it works normally only to freeze again after a while.

It's a clear indication that trial period is over. Probably you forgot to mention this.

If you continue work with IDE after 14days period, it blocks all the commands.
