[Plugin: Yoast Breadcrumbs] Uploaded but now code showes in Header and can’t log in to admin

Hi Joost,

I uploaded breadcrumbs at about midnight through the automatic plugin installer in wp 2.7. It must have installed wrong because now my site https://www.DenversRealEstateNews.com shows the breadcrumbs code in the header and has moved my Sidebar2 down to where sidebar 1 ends! PLus I can’t login to admin anymore. I’m freaking out can you help me? Obviously I’m a newbie and this is aprobably a really easy fix.

Here’s what I’ve tried so far: deactivated plugin– no change
added a return to the custom.css at my host just in case I missed it– no help.

re downloaded plugin and activated- no change
deleted plug in and code from custom.css -no change.

please help.
