I initially used dayZ commander and downloaded namalask (latest) dayZ (latest) and arma 2 (latest) and had the problem. I noticed the server I was trying to connect to was running a slightly older version of arma2 and so i got dayz commander to download that version and still had the same issue. Following that I posted here and then tried the 1.62 + beta patch with no luck. I'm currently reinstalling arma and will try again from scratch.
