No Internet in Windows 7 (Mac)

Hi,
I recently upgraded parallels to the latest edition (Version7) and now when i boot up windows 7 in my mac(new macbook pro with the latest Mac OSX) i have a slight problem. At home on my wifi signal windows runs fine and i can access the internet through it, but when i am not home or on wifi i use a usb internet stick. When i plug it in it asks me which operating system would i prefer. When i select mac and load up the usb software and connect to the net it works fine through OSX but no signal through windows. So then i tried to open it in windows and run the software and again not. It says that the device has been removed or disconnected. I can see that windows recognizes the usb stick as being attached but i cant get any further. There are some programs in windows that i need when i am on the road and now since the upgrade i can no longer access. Is there a way to A) whilst using the usb stick in Mac OSX to give windows sufficent privilages to use that signal OR B)get windows to boot up the usb and connect and allow OSX to use it? It worked perfectly with the old parallels with absolutely no tweaking. Cheers!!
P.s. I have clicked the start menu,clicked into devices,network and selected each one of those options and none of them seem to work. Any help would be HUGELY appreciated!
