Game just will not launch, and I have no idea what to do!!!!

So basically, one day I was trying to get into battlefront like normal, I press the play button and it changes to that stop button for like a good couple of seconds (the button that if you press it exits the game while you're in it), and then it goes back to the previous play button. During that couple of seconds that it would take to go from the play button to the stop button and back to the play button, there is a screen that says EA at the top with nothing else on it. That screen stays up for a couple of seconds and then disappears.

I have looked at some of the advice given to people experiencing similar issues to me, but I don't know what exactly I should do. I really don't want to go through the process of uninstalling and reinstalling battlefront again due to the fact that it takes pretty much an entire day to install, and I'm worried that if I do decide to go that route, then all the progress I have made in that game will be lost. I do consider myself to kind of be a noob to computer things and this is a problem that is completely new to me, and I just have no idea what to do.

Also, I think I should note that when I enter the EA app, it says there is a problem with my account, and it tells me to log back in even after I check the "remember me" box. After I sign in, I go directly to my apps only to discover that it says I have 1 app, but it doesn't show what app I have. I then try to search for battlefront on the game search thing, and it said I had the game but when I tried to click on the game EA says, "something went wrong, try again later." 

I honestly just have no idea as to what I am going to do about this, and I definitely 100% need all of your guys' help.
