Hi everyone! I'm new to SimpleViewer and had installed the beta version on 2 web accounts. one is mine  which doesn't have any problem but the other which I made for a friend only displays the following message:

This SimpleViewer gallery requires Macromedia Flash. Please open this post in your browser or get Macromedia Flash here. This is a WPSimpleViewerGallery   :(

I don't know where I made a mistake since I just made the same procedure on both sites.

Please help. Thanks!
