How can we buy these Valiant Sale units when the game keeps crashing?

I've crashed numerous time on all my toons, but one in particular keeps crashing again and again. Gree's programmers are so bad that I can't spend money on KA. Maybe someone's trying to tell me something, lol

I bought one of that unit and succesful. I check its in my inventory already.
