The physics engine object doesn't show up in the object list when I search for it. The other physics objects, like the treadmill and the particle object, do show up. When I click the manager, it shows up as not installed when I search for it, and has no option to install it. I tried updating to the latest version, and it is still not installed. I have no idea what could have caused this, and I haven't seen any problem like this on the internet.
I don't want to reinstall the program because I have already installed it on several computers and I'm worried that my serial number may be used too many times.
Is there any other solution to this problem? Perhaps a file that I could get off of another installation of the program on a different computer?
