The first screen means that the program does not see anything in the scene that has a dForce property. If you buy something that says it is dForce, it will come with the dForce property in it. For things that don't have the dForce property, you can apply it yourself, but it may not work.

The second screen means that the part of Daz Studio that does dForce has not yet been made ready to work with your video card. Just click 'yes' and the program will configure itself to work with your video card. This is normal and the way the program is designed to work.
