My program is more or less frozen. I can’t close the 3D Warehouse or Extension Warehouse Windows, I also can’t save my model which I have spent HOURS working on. When I hit the red button in the top left to exit it does nothing. The save window opened, and I can type and access it but when I hit SAVE nothing happens. I know I should have saved earlier. Classic problem. If anyone could help I would really appreciate it! I have to hand this assignment in tomorrow.
