Visual Form Builder Pro Not Displaying Correctly in Twenty Ten

I am using the latest version of Twenty Ten and WP.

I am having an issue with displaying a form made with the Visual Form Builder Pro plugin. Inside the site, the preview looks like I want, but when I view it on the live site the fonts and colors are not showing correctly. The layout and the content is fine though.

The author of the plugin says it has to do with CSS restrictions on this theme and that I should ask the author of the theme if there is something I can change.

This is what the form should look like. This is an actual preview accessed from within the site:

This is what it looks like on my site:

Is there anything I can do in Twenty Ten to make this form show the way I want?
