The source package for version 0.9975-10 Matrix has just been moved
onto CRAN.  Binary versions should hit the mirrors in a day or two.  I
suggest you try with that version.

In the meantime try

str(get("Logic", "package:methods"))

I get

Formal class 'groupGenericFunction' [package "methods"] with 9 slots
  ..@ .Data       :function (e1, e2)
  ..@ groupMembers:List of 2
  .. ..$ : chr "&"
  .. ..$ : chr "|"
  ..@ generic     : atomic [1:1] Logic
  .. ..- attr(*, "package")= chr "base"
  ..@ package     : chr "base"
  ..@ group       :List of 1
  .. ..$ : chr "Ops"
  ..@ valueClass  : chr(0)
  ..@ signature   : chr [1:2] "e1" "e2"
  ..@ default     :Formal class 'MethodsList' [package "methods"] with 3 slots
  .. .. ..@ methods   : list()
  .. .. ..@ argument  : symbol e1
  .. .. ..@ allMethods: list()
  ..@ skeleton    : language function (e1, e2)  stop("invalid call in
method dispatch to \"Logic\" (no default method)",  ...

The Windows binary version of the Matrix package that you installed is
several weeks old.  If it didn't install on a stock version of R-2.4.1
I imagine we would have heard about it before now.  I think you may
need to check if somehow you have an old version of the methods
package on your search path or just install a fresh copy of R-2.4.1
