My "Logo" Keeps Dissapearing

I’ve yet to officially launch “www.accessole.com” (using the Novelti theme) however I’m having trouble keeping the word “Accessole” on the top left of the home page. It’ll stay for a day at the most then it returns to the default, “Novelti”. Any suggestions?….Also if anyone knows why my site seems to “grey out” as if a pop up occurs (even though there isn’t one) thus freezing my site, it would be greatly appreciated.
