The only thing I think you can do before contacting support would be trying it on low res mode. If that doesn't work try to contact support@rovio.com.
Tap the book on the bottom left of the screen. Then click the gears at the top right of that window to open settings. There should be an option to check low detail mode. I'll log on and see what it's actually called.
