I'm not really sure what is the problem 'cause I was playing the game just fine a couple of days ago then suddenly this happened. I already reinstalling both Java and Spiral Knights but it's still the same thing.
Like, whenever I click on it, my screen just flashes and it's like changing revolution in each flash then nothing happens.
I also looked for an error code and this is what I got:

Now I'm not too sure what to do. Any suggestions?
A little info of my computer:
Windows 7
AMD RADEON HD 7670
4 GB RAM
Intel i7 2.30 GHz
Had a similar problem, and I updated my drivers for my graphics card. Then it worked.
There are links to driver updates for different graphics cards on the "Technical problem? Read this first!" http://forums.spiralknights.com/en/node/48 Sticky thread of this forum. There is no link to AMD drivers, however. Use that link, which has more information on it to make sure you are installing the right thing.
If that doesn't work, I don't know.
This seems to be an issue that stems from the close of the March of the Tortodrones event mission on the 9th. I don't know for sure if that is true, but you and I are not the only ones that have/had this issue or one that is similar.
