Unity 3.0 in Windows XP can't change the built webplayer name

In unity 3.0 on windows xp you can't change your webplayer name when you build it. It asks for a folder to put the webplayer in. Then in that folder it makes another folder and calls it WebPlayer. If you try to change those names in windows and put it on your ftp to call it from the web it wont open. But if you dont change the name and stick with the Webplayer.html name and call that it works fine. So how do I make webplayer in 3.0 change the name I want and use that instead? Thanks.
