EDIT: Okay thanks again i will try that.
EDIT2: I deleted all the files in public_html and reinstalled, it comes up with the same error, and the files appear. I think its missing loads of files because i cant see a plugins, themes folder etc. when im in the file manager, and the admin folder just has index.php in it :\
