When I select the shortcut for spiral knights or launch it from steam, it pops up the launching window momentarily, then it opens the game window, as usual. When the game window appears, however, it is completely black (until I edited the registry to turn off fullscreen my computer screen would turn black). Moments after this blank window appears, it disappears. If I try to launch the game again, steam will tell me that the application is already open or something to that effect. Checking the task manager, java is running, although the game is nowhere to be seen. By terminating the java process, steam will allow me to launch the game again, however the issue repeats itself. I have tried deleting local game files via steam and reinstalling to no avail.
