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'
