What is ActivInspire?I need the board to work!

Hi Natalie
When there is no power to the flame on the ActivBoard this is usually related to a cabling issue or power issue. 
Have you tested a different USB cable at all? If you have an ActivBoard with built in speakers, does the amplifier have power on the left hand side of the ActivBoard? 
Should the issue persist I would recommend contacting Promethean Technical Support directly for this issue.
