when I select import, a window comes up titled "select a source" I don't know where it came from or how to get rid of it..
The more details you can provide, the more likely it is that you will receive the help you need. And posting separate threads only confuses things. From what you have described, it sounds as if you have the compact import dialog displayed. In the lower left-hand corner of that dialogue there is a little down arrow that will expand the import screen into the full import dialog.
If that isn't the problem you are facing, please respond to this message and explain more fully what is happening.
