So after my pc decided to die, i bought a new brand new pc, after that i needed to install everything back again. But after i've downloaded tf2 back. I opened hammer to check if it worked. Starting the program itself up wasn't the problem, but when i try to place a texuare with the block tool, it will instead turn into the shape of it, invisible and outlines. Maybe because my hours with hammer are about around 60 i haven't got enough experience to figure it out but, but does someone know the answer on how i could fix it. Thanks.
