Cannot install theme in EasyBlog as error message comes with saying same folder exists in theme folder, help!

I have easyblog installed on my website and have purchased a template to use for the blog page. However when I try to install a theme in the EasyBlog section, it comes up with the following error message

"There was an error installing the theme as the same folder exists in the themes folder."

I cannot find anyway to get around this so please can you help?

I have a template currently in use, so this new template is an addition and only to be used for easyblog which i am told isn't a problem.
