Issue with AD6641 Eval Board and SPI Controller Software

I am going through the getting started guide (document UG-292) for the AD6641 eval board and HSC-ADC-EVALCZ. I run into an issue when trying to configure the SPI Controller Software (page 8). When I first open the SPI Controller software I am prompted to load a config file. I select the AD6641 config file but I get the following error “Read Test Failure. Chip ID is not known. NewDUT() will not proceed. Check Chip Select # or USB cable. Cfg should be re-loaded.” I tried resetting my computer, the software, the boards, and the USB connection with no luck. When I press the “Read” button in the SPI Controller main interface it reads the wrong ADC “AD9246, 14 bit 125 MSPS.” I believe that I have P200 and P400 on the AD6641 eval board set correctly as per the instructions. Also it seems that the FPGA on the HSC-ADC-EVALCZ programs fine via the USB connection. Any help would be appreciated.
