Settings in AOL Desktop Gold?

I recently downloaded and installed AOL Desktop Gold (Revision 11.0.3316) on a new desktop personal computer (Windows 10), and so far everything except 1 very important thing works fine.  That one important thing that won't work is the "Settings" button.  When I click on it, nothing happens.  And when I click on it again (2nd attempt), all I get is a black blank screen that I can't do anything with!  Please help, as I would really appreciate it...thank you.
