Hi Mel.
Are you trying to load a flipchart from a USB Pen drive at all?
On the ActivTable, under the Windows account you have the ActivInspire software which will allow you to run flip charts should you choose to. You will need to have a USB drive plugged in to your ActivTable and then choose File>Open within ActivInspire and select the location of the pen drive.
I hope this information helps.
