Having a weird issue with the durability option. When I select a weapon, it shows it as having full durability in the gameplay screen. But when I go to my inventory, the weapons I've selected with this cheat activated are shown as being at half durability (even if they started at full before I turned on the cheat).
EDIT: Hrmm.. nevermind. While the icon shows it as being at half health for some reason, the item list shows them as being at 100%? Odd.
Go to your internet options before you launch a game, you can set it to single player only, as well as VAC on or off if you're leaving online open. If you're having trouble playing MP on steam, set up a hamachi server with your mates and play LAN only, they should show up.
