Hi Belly,
There are two possible causes to this:
1. In correctly patched file. In this case reinstalling the app (or clearing the app data on android devices) can trigger a redownload and fix the problem.
2. Not enough memory to load the stage, which some chapter 5 stages can take a bit. If you are using android device with only 1GB ram, you probably want to kill all other apps running in the background before attempting again. If that doesn't help you can try another device or run the stage on the free android emulator
