LOVE but..... – Squaregram - Layouter for Instagram Review

I LOVE this app. It is the only editing app I use. However, when I go to import existing, and select a photo from my camera role, it won't select the photo... It's like it just freezes. I'm not sure what this is because this all has worked fine for me until now. If you could fix this for me it would be greatly appreciated:)
