Lol please take SS of the error and post it here. I have never heard of that and that doesn't make much sense. Did you download the app using a different iTunes account than the one your using now?
to become unsilenced, you must wait a bit before emailing support@AThinkingApe.com
to appeal to be unsilenced stating:
Why you were silenced
Why you want to be unsilenced.
I can't remember the rest.
