@Cricket: Sorry I don’t know how your Free version used to look like after the customization. But I can suggest you the css based on your requirement to your site.
1. First delete the following css from “Appearance => Theme Options => Custom CSS” box:
#site-logo, #hgroup { display: inline; float: right;}
2. To make the logo left, go to “Appearance => Theme Options => Header Options” and then uncheck “Move Site Title and Tagline”.
3. Then add the following css in “Appearance => Theme Options => Custom CSS” box:
.logo-wrap { display: block; width: 100%; }
#site-logo { float: left; width: 50% }
#hgroup { float: right; width: 50% }
#branding #s, #branding #s:focus { width: 270px; }
