Getting the DMA Interface for PCIe to work with the Arria 10 GX FPGA Dev Kit

Hello All. I am trying to get the DMA Interface to work with the Arria 10 GX Development Kit. I downloaded the reference design (https://cloud.altera.com/devstore/platform/16.0.2/standard/an708-pcie-gen3x8-avmm-dma-with-external-...) from the design store, and I downloaded the driver/application (http://www.alterawiki.com/wiki/reference_design:_gen3x8_avmm_dma_-_arria_10) from the alterawiki. I was able to successfully compile the reference design on Quartus and program the FPA, and then I built the linux driver by following the directions described int he wiki. When i tried to run the driver, I am getting the following message in my terminal: "couldn't open the device." The wiki doesn't have any troubleshooting information about what this message means or how to resolve it. I am running CentOS 7 and the board is connected to the host through both USB-Blaster and PCIe. My guess is that the driver is unable to connect to the board through PCIe, but I am not sure how to tackle the issue. Any help would be much appreciated! Thanks.

What is showing up when you execute "lspci" on the CentOS terminal? You may need to reboot after programming the board.
