Driver for Stratix II Kit

Hi,

I have stratix II Transceiver Signal Integrity development kit. ( 2sGX90)

http://www.altera.com/products/devkits/altera/kit-signal_integrity_s2gx.html

Problem is that when I connect the USB cable pop message display on PC ( Dual RS232 ) and ask for driver for that. I think that driver comes with CD but I don't have CD and I can not find the driver on alter web site.

Let me know if any one found driver for that on website so that I will able signal integrity software comes from CD.

Regards,

Hardik Sheth
