I've been using the demo for Cinema 4D R19 Studio without registering it and had no problems. Today, I registered it, so that I could save the file but now I can't select my model.
Left clicking does not select anything in the view port, but when I click and drag the perspective camera rotates around the point I'm clicking.
The model is an exported model from a different 3D program, but I have changed nothing on the model between using the demo unregistered and registered.
Even if I create a cube in a different file, I cannot move or select it within the viewport. If I click the movement handles and drag up, the camera just zooms in. Something must have changed during the registration. I've even tried deleting the preferences to reset them.
Did some feature get activated now that I need to turn off? I've been searching the internet for a while now and can't find anything. Any help would be greatly appreciated.
EDIT: Updating my Graphics Card did the trick.
