My b2evolution Version: 1.10.x

I'm on2.0 Navy Pier

When I switch skins (miami_blue that installed fallowing the instructions) I get this error when I load the Blog:

Warning: require(/nobel/raoul978/b2evolution/blogs/skins/miami_blue_tuto/index.main.php) [function.require]: failed to open stream: No such file or directory in /nobel/raoul978/b2evolution/blogs/inc/_blog_main.inc.php on line 482

Anyone has an idea of what it is ?
