I am Korean. I can not speak English very well.
So please excuse.
Delete the program.
Restart the system.
Must delete the program folder.
And Reinstall.
Although not exactly understand your words, I'm one kind of advice you to be.
If you created a C3D project file by Ulead COOL 3D Studio. That C3D project file named "A".
Now, you can open it sucessfully by Double Click at Ulead COOL 3D Studio.
But if you open "A" file by Double Click at Corel MotionStudio 3D, you can't open it sucessfully.
A very complex project file or from time to time(or sometimes), you will see an error message.

So, if you want open "A" file sucessfully at Corel MotionStudio 3D,
you don't Double Click it.
Because "A" file made by Ulead COOL 3D Studio. Not Corel MotionStudio 3D.
I guess, Ulead COOL 3D Studio and Corel MotionStudio 3D are each slightly different in detail.
So first, execute the Corel MotionStudio 3D. And second, program main menu,
File - Open - "A" C3D File. Please note that the benefits.
