Ok, so I've only ever had this problem once before. But now it started up again.

I opened Spiral Knights. The music started playing, but I was only given a black screen. When it got to the Logging In screen, the picture (the background with all the gears spinning) wasn't animated - completely frozen. Every 5 or 6 seconds the music stops for about a half-minute. It's still stuck on the Login screen, freezing like crazy. Can someone help me please?

Edit: Also, if I want to close the program and restart it, I have to use my Task Manager. When I open the game back up, the issue still arises - freezing, music glitches and unplayable screens.
