Do you get any errors, pop-up windows, or anything else which could give us a direction to follow? Without information it's difficult to diagnose the problem.
actualy nothing at all. once you click on a wall or anything and to try to change its material, nothing comes at all. doesnt want to. I tried to repair and reinstall and nothing happens.
yes but i couldnt understand the second option, reinstalling and repairing and changing scale dont work. but how can i do that 2nd option? where can i find those things to click on them? is it in program files?
