Update Camera Raw to 4.6, either using Updates from the Help menu or download from here:
Make sure when you insert a card into camera, have that camera format the card. Just because they are the same make does not mean they use the same formatting and so information may be garbled.
The latest camera plugin for photoshop elements 6 is 5.6,
contrary to what it says on the adobe camera raw page.
If you have a mac you have update both bridge and photoshop elements.
Each one uses a seperate camera raw plugin.
The check for updates will work from bridge, but not from the photoshop elements editor.
In the photoshop elements 6.0 editor you can check which version of camera you have.
Go to: Help.About Plug-in and choose camera raw.
I think photoshop elements 6.0 shipped with 4.4.1, which reads d60 files.
Still it would'nt be a bad idea to update.
When you said unable to load, do you mean to the computer or unable to be
read by photoshop elements 6?
