Listary 3.1.477, function flaws, crashes

I have just given Listary Portable 3.1.477 a try on Windows 7 Home Premium 64 bit, SP1.
The first thing I noticed is that I can add an application, but on the next run of the options dialogue, it's gone.
The hotkeys (ctrl-shift-r for command shell, ctrl-shift-t for toggle file extensions for example) do not work, neither in Explorer nor anywhere else.
The shortcuts (/cmd, or /add) do not work.

After all, the program keeps crashing in different situations, e. g. clicking the items in the options dialogue, pressing Win-W and typing, trying to configure an application.

Most probably those are all Listary problems, not PA or launcher problems. However, on their site, there is only an instructional video, but no support forum where users can exchange their experience.

I like the features of the tool, but if it keeps crashing on me all the time and most of the announced features don't work, it's useless for me.
