Your corpus file is way too small. How many sentences does it include? And on the other hand your dictionary is way too big. Even if it does compile OkBoard will crash with such a huge dictionary.

My corpora has a filesize about 200MB and contains around 2000000 sentences.
My dictionary has a size of nearly 1MB and contains around 100000 words. I tried a dictionary with 17 million words(size was around 30MB i think) and OKBoard crashed everytime i started it.
