Try exiting your overclocking software and then try the game, this also was another fix for me..

Hey i managed to fix this issue by reinstalling DX in the arma files:

Hey i managed to fix this issue by reinstalling DX in the arma files:

doesn't matter, i have found that every game cuts out my internet on multiplayer :(

I have just got this bug as well, i have over 750 hours on Arma 3 and its my favourite game, i also run a unit Zeus server for realism ops. I recently moved into my university house and every time i click on multiplayer or try to join a friend through steam the internet crashes, Arma 3 is now unplayable for me and now my unit has no server running for them. I cannot find any solution on the net and that other people have the same problem with no avail.
I really don't want to leave Arma due to this bug, i will post any stats on my internet if you need them.

                                                                                            :(

^^All of the above has gone faulty after the latest patch btw^^

Face, voice and insignia also go missing from Zeus sometimes..

Another Zeus problem is that sandbags and H-barriers have been removed in single items, the only way to place down sandbags is to put down a group of items which contains these things...

Empty on the single items list is also missing, it also says friendly fire when the zeus kills a player when controlling AI, this has a been a problem since the last big update. I am pretty sure this could be fixed easily, Zeus missions are now become less and less special as we have to use the land that is already been used before. BI please fix quick!
