Trouble Connecting to BrainMaster
In order for Particle Editor or Inner Tube to connect to BrainMaster you must insure that you have loged into BrainMaster with a BrainMaster passkey that allows access to the Particle Editor / Inner Tube programs.
Display Not Smooth
If you have a 2-screen display make sure that the Particle Editor display is on your primary monitor. You can change which monitor is your primary monitor by going to:
Control Panel -> Appearance and Themes (if you are in category view) -> Display -> Settings. Click the "2" monitor and choose "Use this device as the primary monitor" (or click the "1" monitor and choose this to switch back).
If the display is still not smooth you may need to purchase a new graphics card. I recommend a new nVidia or ATI card. You should pay about $60-$120 for a good graphics card. Also try shutting down other active programs, or restarting your computer.
