Problem being solved.
Download CocosBuilder source code, using Xcode open, find CocosBuilderAppDelegate,

About setupResourceManager methods[[NSBundle mainBundle] loadNibNamed: @ "ResourceManagerPreviewView" owner: previewViewOwner topLevelObjects: & topLevelObjs];

Replace bits:
NSNib * aNib = [[NSNib alloc] initWithNibNamed: @ "ResourceManagerPreviewView" bundle: [NSBundle mainBundle]];
/ / NSArray * topLevelObjs = nil;
if (! [aNib instantiateNibWithOwner: previewViewOwner topLevelObjects: & topLevelObjs])
{
NSLog (@ "Warning! Could not load ResourceManagerPreviewView nib file. \ N");
return;
}
[ANib release];
[TopLevelObjs makeObjectsPerformSelector: @ selector (release)];

Running OK.
But not publish APP, further studies, at least temporarily be used. Results posted.
