I keep getting a flashing full-screen when I try to start up Spiral Knights, like its trying out all the different screen resolutions, and when I do what is written below, there are only 2 Registry keys, a language one and a Default one. Can anyone help?

5. Are you getting a black screen/a malfunctioning full-screen/bad resolution?

You will need to try and set Spiral Knights to its minimum display settings:

Close Spiral Knights (if it's running).
Click on the 'Start' menu and then click on 'Run'.
Type in "regedit" and hit 'OK': this will bring up the Registry Editor. Warning: Please do not change anything else in the registry since it could cause severe problems.
Browse through the registry tree and expand to 'HKEY_CURRENT_USER\Software\JavaSoft\Prefs\projectx'
Double-click each of the below registry keys (if present) and type in the corresponding value:
display_mode = 1024, 600, 32, 60
fullscreen = false
render_quality = /L/O/W
vsync_enabled = false
antialiasing_level = 0
Close the Registry Editor and start Spiral Knights.
