Same here, have the GOTY version, and the latest trainer and it does the 'activate', 'deactivated' thing sraight off. I have a-virus off and I've only just finished a rebuild. Still no luck. Any suggestions from the creators??
I had the same issue, but then I downloaded the other version of the trainer (the Retail version, even though I have the Steam version installed), and *that* version of the trainer worked correctly. I suggest trying that.
WOW really? I should check that out I got GOTY edition using steam.
Edit: Nope it didn't work still the same for me activate one second later deactivate.
I am having the same issue. I bought the game on the current steam sale, installed it and it won't activate. I use other trainers with no issues on other steam games. I uninstalled IE10 and went back to IE9 with no luck. In the trainer window it says on the bottom: "trainer and game versions do not match. Please check versions." I have disabled my anti-virus and firewall for testing and tried the other versions of the trainer. I am running Windows 7. I have ran both the game and trainer as admin and went through the trainer troubleshooting guide. Is there anything else I can check?
