That is normal. The next to last hop will always show 100% packet loss as that particular router ignores the "ICMP ECHO" packet, which is always optional.
Are you running any type of anti-xxxx software? Try renaming the "ahiiterr" folder and let the game download the terrain again. If that fails, rename the "settings" folder and see if that fixes it. If that fails, reset the "Maximum Texture Size" to a smaller value.
