R help - Sep 2010 - problem opening pdf device on Windows 7

I can not open PDf device. Acrobat is closed. I have checked archives but 
could not find a solution. What should I do?
> cont.cdfplot("myanalysis.pdf", myanalysis$CDF,
ylbl.r="Stream Length (km)")
Error in pdf(file = pdffile, width = width, height = height) : 
  unable to start device pdf
In addition: Warning message:
In pdf(file = pdffile, width = width, height = height) :
  cannot open 'pdf' file argument 'myanalysis.pdf'

Then I tried:
> pdf()
Error in pdf() : unable to start device pdf
In addition: Warning message:
In pdf() : cannot open 'pdf' file argument 'Rplots.pdf'

And your working directory is writable for you? Otherwise, "Change
dir"
from the "File" menu to somewhere that is.
