Can not install slime for emacs on my windows-7-64

Hello everyone
    I download lispbox ( http://commonlisp.net/project/lispbox/
<http://common-lisp.net/project/lispbox/> ) lispstick (
http://www.iqool.de/lispstick.html ) .When i run them on my windows
7-64,they all shows the same error:
Debugger entered: (("Error in timer" slime-attempt-connection (#<process
inferior-lisp> nil 5) (file-error "make client process failed" "too many
open files" :name "SLIME Lisp" :buffer nil :host "127.0.0.1" :service 33947
:nowait nil)))
  (condition-case data (apply fun args) ((debug error) (debug nil (list
"Error in timer" fun args data))))
  slime-timer-call(slime-attempt-connection #<process inferior-lisp> nil 5)
  apply(slime-timer-call (slime-attempt-connection #<process inferior-lisp>
nil 5))
  byte-code("r\301 \302H \303H\"\210)\301\207" [timer apply 5 6] 4)
  timer-event-handler([t 21620 23714 532000 nil slime-timer-call
(slime-attempt-connection #<process inferior-lisp> nil 5) nil 0])

  When I try to add (url-retrieve "http://google.com" 'print) to .emacs and
then run emacs,it shows the error:

Warning (initialization): An error occurred while loading `f:/lisp/.emacs':

File error: make client process failed, too many open files, :name,
google.com, :buffer, #, :host, google.com, :service, 80, :nowait, nil


  I asked the author of slime,he said it is not a slime bug.So I want to
know what's the error and how to fix it.
