Instead of ${CR} maybe try a "y" (for yes). Note that it's best to do a "y" after a "wr" also, in case it prompts you to overwrite a config from a different IOS version. If that doesn't work, try it with a dummy command like "dir" after it.
Still longing for the good old days where NCM didn't collapse multiple returns in your script down, don't like having to play with it to get it to work!
