Where can I download the Windows 7 driver for RETAIL PLUS Wireless G USB ADAPTER? - driver windows 7 da-vc211a

I use the Vista drivers, but Windows 7 64-Bit Edition. And it is that causes the blue screen of death (non-conducting or less). No drivers are on the company website are available and will respond to my e-mails. Thanx
