I have the same problem too and now i found the solution.
In your flash file you have to specific where the selected gallery's xml file is located.
_root.xmlDataPath = "folder/gallery.xml";

Thanks for your suggestion jack, hopefully someone can help.

Is it possible to import the viewer.swf into my own flash file and use it as a movieClip?
My container flash file will have a list of buttons when user click on each button, the viewer.swf will load into a moviclip that is located below the list of buttons.
I try to do this but the viewer.swf show me "gallery not found".
My container flash file located in the root path and all the photo gallery created by svmanager will located in a folder call images. Is there any solution? Thanks alot.
