It’s probably an internal PHP error. Did you FTP the files to your server? If so did you set your FTP client to use binary mode? If not they may have been corrupted. Also, you may need to change the permissions on the uploaded files to be executable, but that would normally result in a different error.
It’s best to try reuploading and see if that helps first.
