What's up guys.
It's been a while since I've played Dayz SA. I decided to get back online this week but got a little disapointed.

After the latest update (0.51.125720) everytime I try to run the game, it asks me to accept the Battleye EULA. When I hit "Yes" and choose to start it as administrator, the prompt returns the following error:
"Installing Battleye Service...
Failed to start Battleye Service."

Here's what I've tried so far:

• Checked files integrity within Steam;
• Downloaded the Battleye Service .dll from Battleye.com (Dayz standalone specific file) and overrided the older one in /Steam/steampps/common/DayZ/Battleye folder;
• Restarted my PC and tried to run steam as Administrator;
• Deleted every Battleye related stuff from my computer;
• Completely removed Dayz from my computer, re-downloaded it, but still got the same problem afterall.

Is there any idea on how to fix it? Anyone got the same issue?

Hope someone helps me :)

PS: Still using XP due to some imcompatibility with my GPU vs MOBO (It doesn't recognize my GPU on win7, 8 or vista)
