Its the lastest version. "Cartel Tycoon Trainer 0.9.0.1205" from today.
What topic do you mean? Your link brings me into the general discussion page.
And without using the trainer the game works perfectly fine. No issues with it what so ever (so far).
With the trainer activated, so even without using any of the options we are getting "fatal error" to me personally it happens when trying to build stuff and with research.
