Q: NEED HELP -Serial #, password

My hard drive crashed and I purchased a new computer (not a MAC this time - couldn't afford it).  I have an airport express wireless router.  I don't remember the password so I'm trying to reset it but I can't do that without the password.  I logged on to the Mac website and tried to connect with their support (what a joke) staff but I need the serial number on my airport express to do so.  The website says serial numbers are located on a gray strip on the bottom of the products.  Not on this product.  I can't find the serial number through Airport Utility without my password.  Hating Apple with a passion right now.  The airport express is only e months old and wasn't cheap and I'm not in a position to replace it.  Can anyone help?
