For the rest - your photos are just files on a disc. Other than building a catalog with metadata and thumbnails which you wil lprobably lose, there is nothing magic to it and you should be perfectly able to copy and move the files to whatever location you desire and view them in any other app like IrfanView, XnView, ACDSee etc.. If you can't do that, than probably the harrdrive is damaged as well and you need some file recovery tool get working...

Download and install the latest version of Photoshop Elements 10 from
Install and launch "Organize". It would prompt a message that"An older version of catalog found on teh computer. Do you want to convert it." Click on Yes and all the images and videos from Photoshop Elements 3 would be in the new version.
You can use the new version fro 30 days as trail. In between you can purchase the license key for the same.
