Here's my setup:

Macintosh MacBook Pro, 10.5.2
Adobe Photoshop CS3 10.0.1

I downloaded Simpleviewer and drug the folder to Adobe Photoshop CS3-->Presets-->Scripts

I run Photoshop and I look under file-->scripts and I don't have Simpleviewer, I do have swfobject.

I select swfobject and I get the following:

"Error 2: document is undefined."

Then it has a long box that says "Line 8" and basically shows all the code.

I know I have had this working in the past, but I had to reinstall everything on the new machine.

Anyone have any suggestions?
