I get this error when I am sending photos. I have updated the app on both devices and still have the same problem. They are both connected to the same wifi network. The first two sets of 100 photos/videos work perfectly.

Hello. It still isn't working! Can I get my money back???

I am sending from an iPhone 4 to an iPhone 5. I have tried two different wifi networks and leave the app running on both devices the whole time. I attempted the transfers again and I am able to successfully transfer the first 200 pictures/videos out of my camera roll. After that, I get the same error message when I try to send the rest. Thank you.
