I need advice!

Hi, I'm new to this wikia community, so hi! But I have a question. I just downloaded the DMT app on my phone (iphone 4 btw) and it's been on the Check Files screen for a very long time (currently it's been going for 4 hours). I've deleted the app twice and tried again both those times. I don't knwo what to try next and I really want to play!!! What should I do?!
