Duemilanove 328 & Arduino 0017

Hi

I recieved a Duemilanove 328 today and when I attempt to upload data to the board it sends it through COM1 when I want it to upload it via USB however the Tools -> Serial Port menu is disabled. Why is this and how can I fix the problem?

I am running Windows 7 Ultimate, if that helps.

Thanks Matt

Update

I have found a webpage that if you are experienced the same problems as i had just visit http://www.ftdichip.com/Documents/AppNotes/AN_119_FTDI_Drivers_Installation_Guide_for_Windows7.pdf

Have you tried restarting the computer since you installed it ?
