Hello @Mister-HuaJi thanks for your reply.
BattlEye has been known to block loading of certain legitimate files such as Uplay/Connect in the past. Please follow through the following steps from BattlEye's own support page, they advise trying the following >
- Make sure that BEService.exe in your BE Service directory (usually “C:\Program Files (x86)\Common Files\BattlEye”) is not blocked by your firewall in any way.
- Ensure that there is no d3d9.dll, dxgi.dll or dsound.dll file in your game directory. If there is one please remove/rename it.
- Ensure that you have a legitimate copy of Windows. Pirated copies might no longer be supported by the latest BE version.
- Check if your game directory’s file permissions are broken by doing the following: Right-click on your game directory (in Windows Explorer), select “Properties” and go to the “Security” tab. In the group/user list select the “SYSTEM” entry and check if it has full access. Otherwise, click “Edit…” and grant the “SYSTEM” user full access.
- Your system’s root certificates might be broken/corrupted. To fix them download and install the following update from Microsoft: http://support.microsoft.com/kb/2813430.
- Check your system files for corruption and possibly repair them by following these guides: http://support.microsoft.com/kb/929833 and http://support.microsoft.com/kb/947821.
- Scan your system with up-to-date anti-virus and anti-malware software. Malware that modifies system or game files can cause such issues when BE is enabled.
- Googling the name of the blocked file can help find out what is actually behind it. Sometimes BE might block malware/adware/PUP files, which can cause problems such as being unable to find or connect to servers in-game. We recommend Malwarebyte Anti-Malware for removing such software from your system.
- Ensure that you don’t use any tweaked/custom versions of system files (including DirectX). Reinstall DirectX, see the following page for details: http://support.microsoft.com/kb/179113.
