Window Doesn't Appear

So I went to open Musescore a few days ago and when I opened it, the icon on my taskbar showed that Musescore was open (I have Windows 7, so it was highlighted), and when I hovered over the icon, I could see what the window was supposed to look like in miniature form (like you can with any program in Windows 7) but I couldn't see the actual Musescore workspace! I minimized all my other windows but Musescore wouldn't show up. The weird part is that when I open a Musescore file from my directory and hover over the icon in my Taskbar, I can see the Musescore opening my file and switching form the demo to what the first page of my score looks like in the miniature window, but the actual workspace doesn't open. If you click the Musescore icon, it does switch the focus to Musescore, but no window. I uninstalled and reinstalled Musescore and it worked fine, but after I closed Musescore and tried to open it again, the same problem happened, so I can't open Musescore or work with any Musescore files! grrr -___-
