Wireless adapter problem

[heathshad]

Hi. I recently installed Windows Vista in my computer. As soon as the installation was finished, Windows automatically installed my Encore Wireless-G PCI Adapter Enlwi-G as Marvell Libertas b/g. I connected to the internet and everything worked fine. After installing a program, I had to restart my computer. When I entered windows again I wasn't able to access the internet. I checked the wireless lans but the computer couldn't find any around. So I went to the Device Manager and saw there was an error with my adapter, it gave me Error Code 10: This device cannot start. I tried installing its driver for Windows XP, the driver fo Enlwi-G2 for Vista, but nothing seems to work. Does anyone have any idea of what to do or have a similar problem solved??
