"Message failed to verify!"
"Error: wrong signature"
Are you sure you posted the message correctly?
Any trailing linebreaks or whitespaces you could have forgotten (tried a few combinations, neither verified).

Yes, you can use it. The format looks wrong though and I think you should show the pictures directly.

How do you get the code format of the message?  Does that have to be done manually?

Yes, you'll be entering the parts of your signed message (message, address and signature) into the blank by hand:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----

Basically, the new blockchain wallet (beta mode) doesn't support this(signing a message) feature ATM as far as I know. There was already a discussion held on this topic(issue), I'd guess.
