I am getting an error when I try to install Rigid- Light responsive. I current have Rigid- Bold but it is not the responsive version, and I need it to work on cell phones. I assume this is happening because there is duplicate code somewhere? Any ideas? I'm new to websites... not sure how to write code etc.

There is a file attached with a screen shot of the exact error (it's long to type out).

Starts with:
"mysql error: [1062: Duplicate entry 'simply_logo' for key 'btHandle'} in EXECUTE...."
