I have a couple of servers that I usually only join as they're usually quite populated and I can usually get in them quite swiftly, but all of a sudden I can no longer join them. Bit of a pain in the arse but I'm sure it'll be fixed in a jiffy (hopefully)

I used to have the problem massively, tried just about anything and everything and still wouldn't work, but I ran it in windowed mode and it was sweet as a nut from then on :)

This is a bit of a shot in the dark but try running steam as administrator

can only assume the install was completely fucked, this is probably the best thing for it. I at least hope your internet is fast for the redownload

Try and run the game :)

yep

Try going into steam and right clicking on arma 2 operation arrowhead, then go to local files and then select verify integrity of game cache and see if that helps at all :)

Can you just run me through what happens when from when you start the game up until the point it does't work?

When you start the game up are you selecting it to launch ARMA II: Combined Operations?

I'm having the same problem, although I thought it was a problem on my end so quite a relief to find alot of other people are having a similar issue, which will probably make it priority number one to be fixed, apart from this I absolutely love this game to bits :)
