It gives me an error every time I want to unrar your files... my anti-virus(Avast) doesn't give me any warnings about it, so I don't know what's wrong.
EDIT: nevermind, it was Avast, one has to disable it, then create a path that Avast won't be allowed to scan where to put the trainer in.
EDIT 2: doesn't work, I open it first, then the game, tried pressing F1 in the main menu, but it crashes after the mission starts, then tried pressing F1 after the mission starts and all I hear is "ping" sounds, and when I check the trainer I see nothing is on.
EDIT 3: managed to get it to work -> start the game first, then start a skirmish, open the trainer, win the skirmish, then you can use it in the campaign too.
EDIT 4: apparently if there's a cut-scene in the campaign, the invincibility magically disappears, and if you try to off/on the trainer again, it crashes... buggy mess, and I'm using the same version it says the trainer is for... clearly it's only for skirmishes which makes it freaking useless because one can easily beat the AI in the skirmishes.
EDIT 5: after many hours of playing it's clear, the trainer works(you can open the game, go in campaign mission/skirmish and then open the trainer and activate it) but works perfect only in skirmishes, in campaign it might make the game buggy while the reveal map will never work in the campaign.
