It keeps crashing!!!

I love this game and want to give it 5 stars, but it keeps crashing and coming up with a "no campaign available" message every time I post a word and I have to restart my phone. Also, a paypal commercial will pop up at random and loop and I also have to restart my phone for that. I seriously cannot believe this hasnt been fixed, do you not care about your users??!
