Well mine got stuck on this after dozens of reinstalls of both java and spiral knights on steam it still wasnt working.

What got it working in the end?

When it was starting up, go to processes, find the java*32.exe or javaw.exe that relates to spiral knights, go to its location, go to its properties, set it to run as administrator, and my game now works.

Why this needs to be done I HAVE NO IDEA BUT IT ANNOYS ME TO NO END.

Lately I've been having trouble with connection and lag. I always have a red bar so I was wondering if anyone else is having this trouble because normally I don't have trouble. Also if you have any tips or info it would be appreciated thanks.

I tried getting on today and the log in stays at one screen, after restarting the game multiple times nothing happens
this same issue goes for my friends who play through steam, whats going on?

As of now we know of two people who cannot run Spiral Knights on Windows 10 over Steam.

I don't ask for an instant fix, because there may be changes to Windows 10 in the near future due to it just being released, but please look into the problem and let us now what your approach will be.

Got reports from a couple of friends that the servers were down - same goes for me. Message is "Failed to connect to server".

Edit: apparently there was an update without notice? Updated and it works just fine.

i was playing spiral knights and mid-game the power in my house went out but it came back on, so i restarted the game to get my connection back but ever since then its been stuck on the logging in screen whenever i click log in. then it freezes and the only way to exit out is to hit the force quit shortcut on my macbook.

i tried restarting my computer, reinstalling standalone and resetting my browser but nothing is working, its permanently like this now and i feel so frustrated because it wouldnt have happened if my power didnt go out.

When I try to log in to SK through Steam, a window pops up saying: "The application has failed to launch due to the following error: Server returned HTTP response code: 403 for URL: http://gamemedia.spiralknights.com/spiral/20150616160405/getdown.txt

When I go to the stated URL there's nothing to download so not sure how to fix this.

I have tried checking for updates and missing files in Steam as well as reinstalling Spiral Knights to not solution :(

Specs:
Macbook Pro
OSX 10.9.5
16GB memory
NVIDIA GeForce GT 750M 2048 MB

Every time I play Spiral Knights these says, my game hangs, and it stays like that. I have to quit the the game, and restart, and this hanging happens almost every 15 minutes. This needs to be fixed, as I believe there might be many other players who are having the same issue.

I'm running Windows 7 64 bit with 4 GB of ram, ATI Radeon HD 4200 video card with 1 GB of video memory, and the game's process quits after the update window (I know because I watched it in the Task Manager). It also happens in the web browser version, and uninstalling and reinstalling does not work, neither does restarting the computer.

Checking the projectx.log file, I get this:
