A) Did you check your internal storage? (It should be under Internal Storage > com.android.cts.boldbeast.recorder > rec
)
B) I have no idea why it crashes when you try to enter settings. I'll try to look into that. You're on an Exalt, right?
C) Just ignore the update prompt. The app works fine, and when you try to hit update it takes you nowhere, so just leave it.
