Features using the Master Database will not work" and after clicking OK multisim opens up and there are no components to select. i have reinstall a few times and i keep getting the same error. what can i do to fix this?

Hello lancee,

• What's your operating system?
• Multisim version (go to Help>>About Multisim)?  
• Did you install Multisim using the default path (C:\Program Files\National Instruments\Circuit Design Suite 10.0)?

OS: Windows XP SP2
multisim: v 10.0.343
and yes, default path.
