Same situation.
I am using windows 10, but have the exact same problem after having installed the free version:
Under the menu 'options', it does refer to 'system-wide-hot-keys' (inbetween 'Controller' and 'Automatic incoming'), yet clicking on it brings me to the tab 'incoming' and the hot-keys tab isnt there.
Would love to use this program again, I last used the program several years back, but remember liking it especially because of the hot-keys.
