Arma 2oa won't launch with battleye

-- When I want to launch arma2oa with battleye (arma2oa_be.exe), the process don't launch and exit with "0xc06d007e" error.

I don't have any problem without battleye. But when I try to connect on a server, I got be service not running.

What I try:

Reinstall Arma2 and oa.

delete /program file x86/common files/ battleye

delete appdata/local/arma2oa/battleye

Delete all arma2 exec and restore via steam

Uninstall battleye and reinstall

My OS:

OS Win 8.1 64

Cordially

I too had this problem out of nowhere and this is what I did to fix it.

1)Uninstall battleye via steam/steamapps/common/arma 2 operation arrowhead/expansion/battleye/UnInstallBE

2)Delete BEclient.dll from Appdata/local/arma2oa/battleye/

3)Delete BEService and BEService_arma2oa from Program Files (x86)/Common Files/Battleye/

4)Verify integrity of game cache with steam

5)Launch game with steam

NOTE: Just be sure to delete the battleye service from Program Files (x86)/Common Files/Battleye. I reinstalled battleye/arma2/arma2oa several times and finally when I deleted the BEService and BEService_arma2oa is when this fixed the problem for me.
