SnipMate in Vim on Windows

What is wrong with my install of snipMate? I cannot get it to work. I even tried installing Pathogen as noted in the other answer. I am running vim7.4 on a windows XP. The _vimrc is noted below -

set nocompatible
set textwidth=80
set formatoptions=cqrol
set ts=2
set expandtab
set guifont:Courier_New:h8:cANSI
set backupdir=$temp
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
behave mswin

filetype plugin on

autocmd BufEnter * setlocal cursorline cursorcolumn
hi cursorcolumn ctermbg=247 guibg=grey70
hi cursorline ctermbg=247 guibg=grey70            

call pathogen#infect()

The VIM install directory structure looks like below. It is after I unzipped the snipMate.zip to vim74 folder.

Solution

Okay finally problem solved. After some reading and trial&error, I stumbled upon this question which did it. The path separator slashes in the _vimrc are "\" by default. But they need to be "/". Thank you those who helped with their answers and comments.

The working _vimrc file is shown below -

"for pathogen
runtime ../vimfiles/bundle/vim-pathogen-master/autoload/pathogen.vim
execute pathogen#infect()
execute pathogen#helptags()

"for snipmate
let g:snippets_dir="$VIMRUNTIME/../vimfiles/bundle/sv-snippets/snippets"

set nocompatible
set textwidth=80
set formatoptions=cqrol
set ts=2
set expandtab
set guifont:Courier_New:h8:cANSI
set backupdir=$temp
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
behave mswin

filetype plugin indent on
syntax on

autocmd BufEnter * setlocal cursorline cursorcolumn
hi cursorcolumn ctermbg=247 guibg=grey70
hi cursorline ctermbg=247 guibg=grey70

Some notes about this _vimrc -

I call pathogen#helptags() in _vimrc because I am sure I shall forget it. I do not have too many plugins so this is not a problem.
During the exercise I stumbled upon a way to locate pathogen in the bundle folder as well. Thank you Ted Reed for this. I haven't seen anybody talk about installing pathogen this way. But it's great because now the install is not corrupted even with the pathogen files.
I did not see any differences in the behavior if I comment out the mswin related statements. But I left it in there because I do not completely know what they do and I have been using it this way for a longtime now without any issues.

The directory structure I use -

c:\program files\vim\vim74 - vim install, given by $VIMRUNTIME
c:\program files\vim\vimfiles\bundle - plugins such as pathogen, snipmate
c:\program files\vim\_vimrc
