¡Hello!, i have long time without playing this great game. I found it, its in me language now, and i want to learn more in the tutorial mode, well, its called training. But now i found a problem in the third training.
The problem in the third training its when i start i click in the building where i can create the rockets, then theres the second window and a next button to go to next step... So i press next and... The button gets grey and i cannot use more. There is no instruction so i can follow to do... So i dont know why its grey.
I have a clean installation without mods, on steam (last version of the game), i have uninstall the game and installed again, verify the game, and of course, exit and enter a tons of times... But the button gets blocked again...
Can someone help me please?.
Here is a screenshot (remember its on spanish): Screenshot
