Hello,
Got a new laptop. The game worked for the first day and then I got this error "unable to find a3client.exe"
I followed solutions as per previous thread. Kept the a3 mania folder in exclusion list under Windows Defender.

Still the issue remains.
There is no antivirus installed.

If I go to the folder and click on A3 client application it says " Smart app control blocked an app that may be unsafe"

Please advise

When I say Windows Defender I mean Windows Security.
Wasn't aware windows updated the name.

Now it says Failed to connect to the login server.
I believe server is down?
