What happens when you try the pathping portion?
Are you playing full screen or in a Window? It's possible that a UAC window has opened behind the client and is awaiting a click for Allow/Deny.
You can paste your tracert/pathping here or PM them to me.
You do have to launch you command prompt as an admin if you received an access denied error. Hold CTRL+SHIFT and hit enter from the run box after typing in CMD.
