Not clear - I can't understand the problem. The message is too vague or cryptic, or it lists too many possible reasons.
	Not helpful - It explains the problem, but not how to solve or work around it.
	Not necessary - It's basically a useless interruption. It tells me things I don't need to know or don't care about. The application could possibly inform me about this in another way or not at all.
	Thanks for helping us improve our messages!
