problem with google checkout functions

[Hilary]

I am trying to start my own on-line shop using google checkout but when I go to the checkout button I recieve the following message

the error reads:
Server Error in '/shop' Application.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

the error is caused on this line:
Dim Resp As GCheckoutResponse = Req.Send()

Does anybody have any ideas that may help me overcome this error!!!!

Thanks
