f8 theme not displaying properly

Hoping someone can help because I cant understand why the f8 theme wont work properly for me. Its the first WordPress site Ive set up and took a bit to get things running, did it in the end. Looked into installing the f8 theme, which installed but its come up with these errors…

Warning: fopen(/websites/123reg/LinuxPackage21/ma/tt/os/mattosgoodphotography.co.uk/public_html/wp-content/themes/f8-static-v1.1/style.css) [function.fopen]: failed to open stream: No such file or directory in /websites/123reg/LinuxPackage21/ma/tt/os/mattosgoodphotography.co.uk/public_html/wp-includes/functions.php on line 4165

The menu bar displays the wrong words (just says ‘link’ for all the pages) and they also dont link to anything. Obviously I can see its a function error but I dont understand what it really means or how it can be resolved. Ive looked through graphpaperpress and think it might be because I dont have Modularity installed.

Is that right? Or is it an issue to discuss with my host providers?

Search all the forums and Google for an answer but cant find anything.
