Alright, after many test with all the tips above it still doesn't work.
I'm running the 64-bit version directly through steam, I'm launching the trainer with admin rights, I don't run any betas. I disabled and deinstalled all mods, i deinstalled and reinstalled the game. I don't run any security software.
Your game exe is identical to what I have here. I even switched them and am able to use our trainer w/o issues.
Unless you customized your Windows OS and ripped out Defender, I doubt that you don't use any security software. As it's either Defender (Win 7+8+8.1 edition), Microsoft Security Essentials or Windows Defender (Win 10 edition).
Should you use Windows 10, then you use Windows Defender, Controlled folder access, Ransomware protection, Windows Firewall, SmartScreen, Exploit protection and Core Isolation. All bundled up in the Windows Defender Security Center.
The only thing not working for me is I'm getting damage to trailers I own plus the cargo. Should this be a requested trainer option?
2 posts above yours - trainer tested working.
Yeah, the cargo still take damage with the new trailer function. The truck and trailer itself are fine.
Please provide a savegame with exact and easily repeatable instructions and the location of the savegame on your hard drive so we can reproduce the issue.
You have to 7z/zip/rar the save file before uploading it here.
