Outlook does not show reading pane of each email.

When I look where you pick whether to display in the right, bottom or off they are all three already checked with a dark black dot.  I can't change these.  I was a Hotmail account that was changed to Outlook.  After many other squirrely things happening, I would normally reinstall the program but I'm afraid that since I didn't buy it but was changed to it, that I won't be able to download it without a charge.  Any suggestions as to the problem?
