I have deleted my antivir just in case, firewall is down and I started the Download on a clean Browser. Nothing changes. 🤔
I just downloaded it and I can confirm that the trainer is included in the package so it's still something on your end.
Windows Defender?
Nope, everything is off. The download size is from the start only 3 kb (before I klick on download it is so small) I don't think it is deleted by something on my pc. 😭
The rar file is 670kb before I click download so something is not allowing you to download the trainer part of the package.
Have you tried another browser? The fact it's stopping it so early seems to point to a browser addon that's not letting you download an exe.
