At first, Spiral Knights wouldn't even load, and just came up with the message, "Multiple instances of this application's installer are running. This one will stop and let another complete.", but when I restarted my computer it seemed to be fixed. But now, when I start Spiral Knights, it just keeps on downloading and always stays at 0%. I tried restarting my computer again, but that didn't work. I also tried completely deleting any Spiral Knights related files and re-downloading the game, which doesn't seem to work, either.
