Specifically, it stops at 0% and then gives an error that says: This application has failed to launch due to the following error: Server returned HTTP response code 503 for URL: http://download.threerings.net/spiral/client/getdown.txt

I've tried downloading the actual game client and opening from desktop but I get the same problem. I've verified Java and Java is telling me I have the latest version for my windows 7 laptop. I haven't tried any other options, so recommendations are appreciated, though it looks like a problem on Three Rings' end according to the error message.

EDIT (September 3, 2013)
I haven't made any changes to my computer, but it seems the problem had fixed itself today. Perhaps my IP address looked funny to Three Rings' servers?

(There’s a TL;DR at the bottom of the post)

I play SK on a mac, through Kongregate. Since Apple had their Java update removing the internet plugin, I am not able to play the game anymore. I've tried downloading the Java version from Oracle, and the download from the applet runs fine. But when I go to launch the game, after all the "applet authorizations", the SK window pops up, appears and disappears repeatedly, and then stops, the applet and application quitting. I've tried to revert to the older version of java, reinstalling Java 7, restarting my computer, throwing it down the stairs (not really), but it wouldn't fix the problem.

I just downloaded the game yesterday, installed the Tattiebogle.net drive, connected PS3 Controller via Bluetooth, and it worked! Now when I try to play again, the game doesn't recognize my controller (Which is still connected to my Mac), and all the Gamepad options says "none." Please help!!
PS: I am playing on a Macbook Pro Version 10.8.4

I got a brand new super computer, but when I play Spiral Knights, the Dust Bunnies have huge black ears, the same thing happened with my old computer, and the Spookats have an odd ring around their "lips" it only seems to go away when I use compatibility mode, which is something my computer does not need to do! It also seems like when I do that the Bunnies ears disappear, any help?

For some reason, the texture for the "energy lock" on energy-activated gates is missing for me. I tried deleting and re-installing SK, but the problem persists. Can anyone help?

That pretty much sums it up, I changed the controls to gamepad, installed it and it won't work, I tried everything, restarting the client setting custom controls, but the thing still won't work, I mean, why even add the option if it isn't working D:
By the way, I run windows 8.

This happens even when I try to play on the main site. No matter what I do I can't see to fix it. All of my drivers are updated along with java, and i have re-installed the game multiple times.

Its all in the title this all started when the new patch was reaslesed about 15hours ago.
If computer specs are needed, i will get them as soon as i can thank you for any help or suggestions.

So a couple of months ago, I converted by account to steam. That being said, I don't have a knight or anything on my website account. But of course, during this update, it decided to screw with me andstop updating. Hat was happening was, so steam auto updates, and Im waiting for it, and it's taking forever, so I check on it, and it appears to be stuck at 99 percent complete, just a mere MB away from completion. And the download speed is 0 bytes. Can someone explain this and hopefully tell me how to solve it?
