Try "Restore default network settings" in the console screen enter (ALT+CTRL+I), this will place the default back to 192.168.0.220 then enter in the Gateway and DNS settings by entering CTRL + ALT + N for the eth0. Then reboot the system CTRL + ALT + K "System restart" to see if this helps.
If this does not work try downloading the DSS Demo-CD from link below and let us know if this happens with the Demo-CD version of DSS.
