I have used the v2.081 text feature. Following are the steps that I use.
1) Load a DXF file. Any file seems to work.
2) Select operating mode. I use the mill mode for my router.
3) Select the TEXT tab.
4) Select the font that you want to use.
5) Enter the text in the input box.
6) Click on the "Drag Text" box.
7) Left Click with your mouse in the drawing area. Create a box by holding a left click and dragging to the opposite corner.

The entered text should appear in the box.
Good Luck!
