[GNC] opening

[tom9940 at earthlink.net]

   I've been using GnuCash 3.1 for some time; yesterday it worked just
   fine. Today when I clicked on the icon on my desktop (Dell Inspiron) I
   got the usual splash screen and the icon appeared in the task bar as
   usual, but that's all. Nothing appeared on my desktop. I can point to
   the icon on the taskbar and see a screen in there like I expect to see
   on my desktop, but that is all that happens. I restarted my computer --
   no help. I re-installed GnuCash 3.1  --  no help.  How do I get my
   GnuCash back?
