I'm a friend of Alucardsown and he's been messing with this problem since the patch went live on Tuesday.
It's giving him a "Non-negative number required" through Impulse when trying to download the patch.
He has disabled his antivirus completely, removed firewalls, port forwarded, bridged his modem, direct connected his modem to his computer, all with the same result.
Whereas I've had no problems with a firewall/router.
I've tried helping him but couldn't come up with anything, even after doing some research on potential fixes.
