[Help - Error] Can't run Freestyle Gunz.

[Nagatobimaru]

Hello there at Freestyle Gunz,
Honored to meet you.

Iam new at freestyle gunz, I have made an account and downloaded the game setup file, I installed as it should be, but when trying to launch the game (start gunz) after launching the launcher and updating, I get the message with title "Gunz.exe" and detailed with only the word "Error".
I have read the help questions and I have done a lot of reinstalling including redownloading the setup file. I have changed the compatibility to window 7 and windows 8 and windows xp for Gunz.exe but still can't start the game, also I have exclude Gunz.exe and Launcher.exe in my antivirus and in the firewall, and tried with antivirus turned off.

I am using HP Elitebook 8470p, i5-3360m, Intel HD Graphics 4000, Samsung SSD Evo 850 250GB, 6 GB of ram, Windows 10 64 bit (Arabic default windows language, writing and displaying -which i doubt will make any difference, but just in case-), Bitdefender Internet Security 2016 as antivirus, and I guess that's all.
By the way, I can run another gunz client (Dark Gunz), which I downloaded and played just to be sure that the issue is only with Freestyle Gunz.
I want to play Freestyle Gunz, and I wish anybody can help me, which I will appreciate so MUCH!
Feel free to ask anything else for details..

I am attaching a screenshot of the issue:

Upload the contents of the mlog.txt file in your FGunZ folder to pastebin.com and post the link here.

Hey Dave,
I couldn't find the file "mlog.txt" in my freestyle gunz directory,
I find a patchlog.txt which i thought maybe could give a hint about the issue, here it is: http://pastebin.com/2uEvB7F9
Thanks.

[Dave]

I assume the same thing happens when you execute gunz.exe directly in the FGunZ folder?

[Nagatobimaru]

Yes the same.

[Dave]

And there's no mlog.txt file at all?
I'll ask one of the coders to take a look.

[Nagatobimaru]

Yup, there is no mlog.txt file at all.
Thanks.

Are you using a paid anti-virus? Maybe try uninstalling it for an hour or so to see if it works without it, that way we also know what's causing it.

[Nagatobimaru]

Yes it is paid (actually get free from sharewareonsale.com), and I tried to deactivate it, and I all already excluded the whole fgunz directory and gunz.exe and launcher.exe...
Do I really need to uninstall my antivirus?

[Dave]

Well.. it will help us to see if Bitdefender is causing it, that way we can see what to do next.
The error is happening because something is tampering gunz.exe when it's trying to start.
