LiveSplit opened once, and never again.

that's literally it. I rebooted my PC, ran as admin, looked it up, and all sorts of stuff; once, and never again.

(Oh, and before you ask, I don't have a XBOX ONE controller plugged in; all I have plugged in is my mouse, and I already tried opening LS w/o it plugged in.)

UPDATE:

Okay, so I found a bit more info on this. The details (as seen in the Event Viewer,) of the error that occurred when I last tried to load LS are:

Exception Info: System.IO.FileNotFoundException
   at LiveSplit.Program.Main(System.String[])

The source of this error is ".NET Runtime," so something's likely up with the code of LS itself, as it's creating a .NET Runtime Error.
My guess is that LiveSplit can't access the file it wants, so it shits its pants.
I might try moving LS into another folder, as that might be the reason it can't grab the file, whatever it is.

UPDATE 2:

Okay, I moved the files to a different folder, and I got the same error from Event Viewer.
Something's seriously broken here, or I've just got some seriously bad luck.

Maybe try to exclude it from antivirus to see if that works. Other than that, I'm not sure what the issue could be.
