error message on trying to upload new theme

Hi,

Very new to wordpress. I uploaded a new theme called choca theme to my hosts server using ftp in Dreamweaver (after unzipping it).

I then went into the admin area and tried to activate it. I got this error message:

Warning: include_once(lib/theme-options/theme-options.php) [function.include-once]: failed to open stream: No such file or directory in D:\inetpub\vhosts\cat-community.com\httpdocs\wordpress\wp-content\themes\chocotheme\functions.php on line 14

Anyone know what the problem maybe here?

Thanks for your help,
