Wikimedia Bugzilla is closed!

I am fairly new to MediaWiki.  I don't see this error posted.

Recently I moved my server to a new machine.  It is running windows, not Linux (the old server).

What I did was take the MediaWiki things (wiki folder), zipped it and then unzipped it at the new server.  In the local settings file I put in the new path (only change) and now nothing works.

(LocalSettings.php file): $IP = "/htdocs/wiki";

The error I get is this:
Warning: dir(/wiki/skins) [function.dir]: failed to open dir: Invalid argument in C:\xampp\htdocs\wiki\includes\Skin.php on line 22

Fatal error: Call to a member function read() on a non-object in C:\xampp\htdocs\wiki\includes\Skin.php on line 27

Thanks in advance,
