Arma 2 Freezes and stop responding

[gummybear_qc 1]

*First of all, I did another post similar but I reported to make the other deleted*

So I got this annoying problem that I encounter on the multyplayer side of arma 2. My game freezes and the only way to close it is to open task manager and end the process. Says arma 2 is not responding, I have encounterd the lrobl while doing the following: 1. Trying to join a server, freezes on the ''Joining game'' window, 2. In the parameters screen of mission when hosting 3. in the

lobby of a server or hosted server. I tried running steam as admin, verifying game cache and using a game luncher. This problem is persistent on Arma 2, OA and CO.

Specs

Os Windows 7 64 bit

CPU: Intel Core i7-3610QM up to 3.3GHZ

GPU1: NVIDIA Geforce GTX 675M / 4GB GDDR5

GPU2: Intel HD graphics 4000 (note im using the 675M to run arma 2)

I really want this annoying problem to be fixed because this restrains my online experience with my freinds, wich is the main reason i

got the game.

Thank you,

So it's just stuff relating to multiplayer then eh?

I'd say check your firewall settings in both windows and the router. I'm leaning more towards the windows firewall though.

+ Anti-Virus :)

Even so they are called "anti-virus programs" they can be pain in the arse blocking your games. ((Specially Avast, AVG, Norton and Kaspersky from my experience))

Well I got bitdefender on this laptop, I had norton on the other one and 1. My oher laptop ddint met the requirements 2. had norton and was working perfectly. Bu I dont think it could be the antivirus or router blocking inernet stuff, because I mean like when I host my server even in LAN does same thing, it dosent shows stuff like connection interupted.Just bam freeze.... :\
