On Install I am getting permissions errors, even after changing all so that all options are green, on next step I get this error message in a red box:

Next files have inappropriate permissions:
ray/modules/shoutbox/xml/config.xml;
ray/modules/shoutbox/xml/langs.xml;
ray/modules/shoutbox/xml/main.xml;
ray/modules/shoutbox/xml/skins.xml;

Also these items dissappear from the permissions list.
Tried various permissions and notheing can get me past this glitch.
