I can't read the message (too small of a pic) but I got this message when I screwed my map folders up. Other than that, I just clicked 'ignore' (Like you said you did) and that's it.
I don't know of a solution. Hope it helped.
edit: Post your 'maplist.xml' file
(Found in: C:\Program Files\Warrock\Maps\maplist.xml)
Maybe that will help.
