What do you mean by freeze? Can you move window around after you press Start button? If yes, then it doesn't freeze. I guess, should have made some progress bar...
My advice is to search at most 1 country, with maximum of 4 divisions (I believe 5th and 6th are all bots). Generally, only number of countries and division affect speed of collecting results. Check the Threaded box (it will use all processor cores). Program is IO bound (there's not much CPU calculations, depends heavily on your network connection). Such configuration takes around 20 seconds on my computer.
