Topic: Picassa simpleviewer template problem, please help!!

I have followed the instructions on the airtight installatiion page to the letter, but the gallery always comes up in picassa format, not simpleviewer format. I do not much like the picassa gallery, it is little more than thumnails with links to bigger versions of the same pics, whereas simpleviewer is much more sophisticated.
Anybody help please?? :? :?
