Fatal Error w/ Adsense Deluxe

I inadvertently activated Adsense Deluxe after it was already activated and I got a fatal error message. I’m unable to access my blog. I uploaded everything from ftp to the blog, thinking this would solve my problem, but it didn’t. I still get the fatal error when I attempt to install from the browser. Any ideas what to do to correct this?

Thanks in advance for your help.
