I cannot in any way update to the latest patch FROM 0.54, therefore I cannot go on multiplayer.
I have tried verifying the cache, re-installing the game, twice.
I have tried loading it through Six launcher also, but it says I have thr wrong version and it get kicked off for bad version, yet I can see all the servers with people in on six launcher.
Please help :(
To "update" to 0.55 (which is DEV version) you need to opt-in to Steam "beta" program for the game (it's called development builds). It's enabled in the game properties - like here: http://img.netupd8.com/steam-eurotruck2-beta-linux-testing.png

You have to switch to dev version for this update.
Right click on Arma III in your Steam Library>Properties>Betas>development build
This version may not stable and it can contain more bugs, than Stable Arma 3 Alpha version.
