Hi,
I use this program myself from time to time, so I will try to help. One thing I am not sure of is whether you are wanting to make an mp3 disc or a regular, CD style disc, so I will go with the regular CD style.
In the main menu/project selector screen you want to click on 'make a music cd'.
Then click on the 'music cd' option.
This should take you to a new window. In the top part of the window is a list of your files. You will want to browse through the little explorer and find the files you want to record.
Then, drag and drop them into the bottom window where it says 'add tracks and audio files here'.
Once you have them in the order you want, just click 'record'.
At that point it will promp you with a few options...if you want to get a regular CD the way you have the items recorded, then click 'disc at once'. That will record and close the disc and then you are done!
If you have any other questions or trouble, fell free to write back. Hope this helped!
