致命的字体规范错误：“cannot-use-pdftex”

Question

大家晚上好，

我在尝试在 TexStudio 上撰写简历时遇到问题。我过去通常按照以下模板撰写简历：

\documentclass[a4paper,10pt]{article}

%A Few Useful Packages
\usepackage{marvosym}
\usepackage{fontspec}                   %for loading fonts
\usepackage{xunicode,xltxtra,url,parskip}   %other packages for formatting
\RequirePackage{color,graphicx}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage[big]{layaureo}              %better formatting of the A4 page
% an alternative to Layaureo can be ** \usepackage{fullpage} **
\usepackage{supertabular}               %for Grades
\usepackage{titlesec}                   %custom \section

%Setup hyperref package, and colours for links
\usepackage{hyperref}
\definecolor{linkcolour}{rgb}{0,0.2,0.6}
\hypersetup{colorlinks,breaklinks,urlcolor=linkcolour, linkcolor=linkcolour}
%add external pdf pages
\usepackage{pdfpages}

\usepackage{graphicx}

%FONTS
\defaultfontfeatures{Mapping=tex-text}
%\setmainfont[SmallCapsFont = Fontin SmallCaps]{Fontin}
%%% modified for Karol Kozioł for ShareLaTeX use
\setmainfont[
SmallCapsFont = Fontin-SmallCaps.otf,
BoldFont = Fontin-Bold.otf,
ItalicFont = Fontin-Italic.otf
]
{Fontin.otf}
%%%

%CV Sections inspired by: 
%http://stefano.italians.nl/archives/26
\titleformat{\section}{\Large\scshape\raggedright}{}{0em}{}[\titlerule]
\titlespacing{\section}{0pt}{3pt}{3pt}
%Tweak a bit the top margin
%\addtolength{\voffset}{-1.3cm}

%Italian hyphenation for the word: ''corporations''
\hyphenation{im-pre-se}

%-------------WATERMARK TEST [**not part of a CV**]---------------
\usepackage[absolute]{textpos}

\setlength{\TPHorizModule}{30mm}
\setlength{\TPVertModule}{\TPHorizModule}
\textblockorigin{2mm}{0.65\paperheight}
\setlength{\parindent}{0pt}

实际上，我无法再编译和查看我的简历的 pdf，因为出现错误“cannot-use-pdftex”。

在过去的几天里，我不得不格式化我的电脑并重新安装所有内容，包括 Miktex 和 TexStudio：但是我已经安装了编译 tex 文件所需的所有软件包。

在格式化之前，我没有遇到过这类问题，我总是使用 PdfLatex 进行编译

由于我是乳胶方面的新手，因此任何建议都是宝贵的。

提前致谢并祝您有美好的一天。
