Title says so, I reinstalled Spiral Knights after a computer crash, and guess what happened?

glitches.
Glitches.
GLITCHES!

Examples

Head, body or both are missing. For the head, only eyes appear.
Freezing during loading. Stays at 92% and never increases.

Could I have some help with fixing these bugs?

All in title

When I go to open fullscreen mode, it shuts down my running SK and doesn't re-open it. I am forced to play in the oddly-shapen browser that opens when I start SK(the square-ish one, sorry if I'm leaving out the dimensions, can't think of them off the top of my head). What could be causing this? It is just my laptop, or an issue with my installed SK?

Typical problem 1.: A java error shows up
-Try to update your video card driver

Typical problem 2.: Downloading errors
-Try to "run as administrator( or something like this)"

Any win 7 problems? write to me, i hope i can help!

I'm able to log in and kind of move around but screen doesn't want to update some of the times. for example, animations are smooth and I can move around for a few seconds, but then the game doesn't update and the screen freezes, buttons aren't highlighted when mousing over them(mouse still works). like it's running fine for 1 second and then it freezes for the next second.
In full screen mode these freeze moments are less pronounced, but in windowed mode, which I prefer, it's unplayable.

Windows 7 - 64 bit
Intel Core 2 Duo CPU
6GB of memory
ATI Radeon HD 5700 1GB

I could connect just fine for the recent update. How can I fix this? I uninstalled and reinstalled Spiral Knights, what do I do?

The game will not launch from Steam. I've restarted Steam, reinstalled the game, used the defragmentation / verification tools, and other java applications work fine. When i hit the play button, Steam will show that i'm in the game with the green border around my image, then turn blue again without even starting the game.

Sometimes i get disconnected from the server. It doesn't happen every day, but when it does happen it is very annoying. Sometimes when I get disconnected I can log back on and i dont get disconnected for the rest of the day, but sometimes, I get disconnected, I log back on then i get disconnected again, then I log back on and get disconnected AGAIN! Then i log back on and get disconnected YET AGAIN! Then i have to wait half an hour to an hour before i can log back on without being disconnected. I don't know whats wrong but I do know that nothing is wrong with my computer.

I run the game, and the patch client works fine, the game starts because I can hear the music and select icons, but nothing from the game shows up-it's not a blank screen, but I can see my desktop and nothing else.

Hi ,

As the title says, i am unable to change the controls from the options. When i click on the Controls tab, my Java crashes.
I can access the other tabs from the options and have tried uninstalling spiral knights, updated Java , reinstall.
