[XeTeX] PLEASE HELP!! XeTeX stopped working

[Alan Jones]

Hi:

I have not used XeteX in a couple of months, Now when I compile any
Xetex related tex files I get this error.

This is XeTeXk, Version 3.141592-2.2-0.996-patch2 (Web2C 7.5.6)
 %&-line parsing enabled.
entering extended mode
(./sample1.tex
! Undefined control sequence.
l.2 \documentclass
                  [a4paper,10pt]{article}
? x
No pages of output.


I wanted to compile my Resume with xemoderncv.cls, but now XeTeX does
not work on any file.

Please help me.

Thanks,
 AJ
