I wanted to claim my Sonic CD items, so I tried booting up Spiral Knights. It came up with a black screen that went to and from my desktop a few times, then just stopped, and apparently the game had closed itself out. I tried redownloading the whole game, and that didn't work either. I tried updating Java THEN redownloading the game, and it still didn't work. I updated my graphics card, and still nothing. I looked all over for help and the only similar cases I saw prompted error messages when the game crashed. I'm not even getting an error message or any message at all.
