10 dollar app... ?

I just PAID and downloaded iWord just now and it wont even open a new or an existing document. I am trying to figure out how to contact the developper (through the link posted on this app store page) but the site isn t in English. So I am hoping they would post an email address where I can ask for support in a language I can understand. So much for thinking of trying out this app. Can I have my ten dollars back at least?
