R help - Oct 2010 - issue with Matrix package

I have an issue with Matrix package.
When I try to load it (with R version 2.10.1 with Windows XP) I have an error
message in return:

 Error in registerS3method(Info[i, 1], Info[i, 2], Info[i, 3], env) : 
  aucun slot de nom "methods" pour cet objet de la classe
"derivedDefaultMethod"

any idea on how I could solve this issue ?

thanks

You have an old version of R and unless you have taken special steps  
(that you have not told us about) to make sure that your version  
(which you have also not told us) matches, then there is quite  
possibly a mismatch between the current version of Matrix and your  
version of R.
