I am completely new to DNN and skinning, and in my first experience working with tweaking a skin, I made changes to the html & CSS of a skin... using only left and right panes. After I  uploaded the new skin (whilst logged in as host) the drop down menu items for admin and host appear, but none of the pages come up.  I suspect the content of these pages is all in the content pane, which I ignorantly removed from the html, hence nothing appears in those pages.

Since I would like to revert to the DNN-Blue default skin, but can't get to the menu to do so, I'm wondering how I might be able to do this easily without the page interface. Also, a child site of the portal is operating okay, so can I somehow affect the parent's skin via the child??? thanks a million...
