General ⇒ Keep getting error `.cls' not found. "Enter File name"

[emilybrick]

I have been using Latex for a while and all of a sudden an error is coming up when I try to compile any of my Latex stuff. This is the error that comes up:

Code: Select all

! LaTeX Error: File `.cls' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: cls)

Enter file name: 

I don't know what file they are looking for. I am currently trying to create a CV, these are my first few lines:

Code: Select all

\documentclass[10pt,a4paper]{}
\include{structure} 

\hyphenation{Some-long-word} 

\begin{document} 

I don't think it's something to do with this though, since other .tex I have is not compiling either.

Any ideas?

Thanks

\documentclass[10pt,a4paper]{}

There is your error Use one of the document classes like article, report or book like

Code: Select all

\documentclass[10pt,a4paper]{article}

mas already provided the solution.

Just an additional advice: Instead of \include, use \input in the preamble, i.e. before \begin{document}. That's because \include is for including pieces of the document body, such as chapters, it even makes a page break before the includes file comes.
