Please help! Yesterday I played a game with my friend. Today I'm banned from FAF.
When trying to run the client, I receive the error below. FAF asked me to authenticate on the FAF website, and it is giving me this error: Ban expires: Never. Reason: Use of prohibited third-party software.
I didn't use any prohibited third-party software. I have no idea what prohibited third-party software I could be banned for, as I can't even think of any. The only thing I could suspect is that I created many single-player vs AI matches recently for mod testing. Also, I used a mod, Sim Speed Balancer, from the vault for 2 days. Maybe this one affected my account...
name = "Sim Speed Balancer"
version = 21
copyright = "Licensed under the FAF Vault License. Free to use and modify."
description =
"Dynamically microadjust game speed to reduce lag and improve performance. Details at https://github.com/Lightningbulb2/FAF-sim-speed-balancer"
author = "Lightningbulb"
url = "https://github.com/Lightningbulb2/FAF-sim-speed-balancer"
uid = "sim-speed-balancer-v21"
exclusive = false
enabled = true
ui_only = false
conflicts = {}
after = {}
before = { "sim-speed-balancer-ui-v21", "CHEESEBERRY-a1e2-c4t4-scfa-ssbmod-v0200" }
I'm always playing vs AI with my friend.
Please help me to restore my access, as I haven't done anything wrong.
