It appears one of two things has happened.
1. Ontrack was able to "recover" the contents of the My Documents directory so you can see the Folders, File Names, sizes, dates, etc. of the the files it contained. BUT it has not recovered the actual contents of each file. If that is the case, can you still access anything on the HDD? Can you use Ontrack to try to recover each file?
2. MAYBE Ontrack recovers things in a particular way that is not quite like a regular file, and you have to do some other steps to get the recovered files ready to use. Re-read the Ontrack instructions to be sure you have done everything required to make the recovered files usable.
