This is the same problem you had on Monday, in the "Error message "got a 
real'" thread.  That's not a .csv file.  Excel recognizes what it is 
despite what you named it, but R is trying to read it as a CSV file, and 
it isn't.

Look at it in a text editor, and you'll see that it's not really a .csv 
file.
