Lost connection to host

[rokyoface]

having trouble logging into servers as of late. hadn't been a problem before but took about a week off and now I lose connection with host after 30 or so seconds in lobby. I believe it has something to do with my battle eye but every fix ive tried has failed.

Hi there rokyoface

What have you tried to fix it?
Have you tried to manually update Battleye from http://www.battleye.com/download.html ?

[OldManTim]

Just had a friend of mine with similar symptoms, and he had to download all the files from Battleye manually.
Go to http://www.battleye.com/download.html
Download all the files for Windows under the ArmA 2: Operation Arrowhead section:

BE Client for Windows (32-bit) - v1.227
- MD5: 5CDAA0521FEF91E82F89E6AF831184EF
BE Service for Windows (32-bit)
- MD5: 3A9EBCA22A0FEE724E3E1166E7FA78DA
BE Service for Windows (64-bit)
- MD5: 56A50CC35D9640D35767FD555E388D02
BE Server for Windows (32-bit) - v1.195
- MD5: D9AF4ECA7CAA01557323B232A2F8A4EB

Copy all the files you downloaded to your Arma 2 Operation Arrowhead\Expansion\Battleye folder
My path looks like this:
C:\Steam3\SteamApps\common\ARMA 2 Operation Arrowhead\Expansion\BattlEye

He then started the game, and all worked fine, no more freezing in the lobby, no more Battleye errors.

Hope this helps!
