I was playing with a dude and he invites to a game with some mates, we join and everything is going fine but then i realise a dude on my team is afk, nothing to sus but hey whatever, I ask if they have a teamspeak they say no they use ventrilo. I though i heard of this before and they send me a link, its a bit wierd but i look it up and it seemed like a thing. I download but nothing happens when i launch it. They send me an ip when for when i get it working. I keep playing. we discuss it not working and they send me a new link. looks similar so i try and nothing happens. I then rejoin and talk to them then i respawn and bam nothing there all items had disapered. I go to trade history and find this guy http://steamcommunity.com/profiles/76561197978059477 half his items are mine. Weird thing is, is he wasn't playing with me. They guy in game made a suspicious remark about it and i left. I deleted the downloads ran a anti virus and changed my pw. but know i cant seem to submit a report to steam. HELP PLEASE
EDIT i looked it up and found this. http://www.ventrilo.com/ seems legit but they said i needed the version they linked.
