[BioC] problems with genome files?

[Manu Bi]

Dear all
 
I am trying to analyse some U133 plus2 generated data but I have some problems and wondered if anyone can help.
My code lines are:
> x <- ReadAffy(myfiles)
> x
 
and I get the message:
 
 Note: You did not specify a download type.  Using a default value of: Win32 
This will be fine for almost all users
 
Error in if ((is.null(deps)) || (length(deps) == 0) || (deps == "")) return(NULL) : 
        missing value where TRUE/FALSE needed
AffyBatch object
size of arrays=1164x1164 features (127026 kb)
cdf=HG-U133_Plus_2 (??? affyids)
number of samples=12
Warning message:

Note: You did not specify a download type.  Using a default value of: Win32

Error in if ((is.null(deps)) || (length(deps) == 0) || (deps == "")) return(NULL) : 
        missing value where TRUE/FALSE needed

 
could anyone tell me what am I doing wrong?
 
thank you
