[R] import csv file problem

[sisxy]

Hello, i am trying to import the csv file into R . 
i have a file saved as csv in my desktop.
My laptop is Window vista, version R is 2.10.1.

then i used the code 
> Q<-read.csv("Q.csv",header=TRUE)

then my error is 

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'Q.csv': No such file or directory

i already search the previous solution....
i am confused , because 
some say for the file name is C:\\Q.csv 
so i change to 

> xx<-read.csv("C:\\desktop\\xx.csv",header=TRUE)

but ,
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'C:\desktop\xx.csv': No such file or directory
> 


any problem for my code ? any problem for the location of the file i saved
or other possible problem that i dont know ? 

Really need urgent help ...
thanks
