[slideshow viewer won't display]

need some help with a slideshow viewer. Just bulk uploaded 17 ppt slides to my viewer. the slides are in the viewer's content folder, but the face of the viewer does not display the slides. What step am I missing here? Thanks.

Thank you both. The second life viewer wasn't displaying properly because windows was not automatically updating drivers. I made a simple change in the default action so that windows does detect and install updates to drivers automatically and the viewer displayed properly and my avatar was 'available'. Your answers got me headed in the right direction.

Registered on Second Life this afternoon. Was notified that 'my avatar was waiting'. Then I signed in. No avatar to be found. I know this sounds pretty silly, but where is my avatar? What am I doing wrong?
