I am attempting to join my buddy's game and it says to him, and only him, that I am a hacker of some kind, and his game won't show up for me in the lobby. I can see every other game that's been started from our room, but his won't let me see it in the list. I don't use any mods or hacks or custom anything, just the most recent version of Garena. I do use Warcraft Version Switcher (WVS version 1.6) in order to make this playable on battle.net when I'm not using Garena, since Garena doesn't seem to use the most recent version. I don't see why that would flag me to him as a cheater. So, what do we need to do to make his game show up for me in the lobby?
Other information below:
OS: Windows 7 64bit
Firewall: Windows Firewall, and whatever is on my TrendNet wireless-N router
Antivirus: Microsoft Security Essentials
Warcraft III and TFT installed from .isos of my own discs, playable on B-Net
Warcraft version updated by connecting to battle.net, downgraded with WVS to a playable version I had stored previously.
