Files was recovered, but not played.

I recovered some mp4 files and figures using free version.

File status was excellent.

However, movie player cannot play mp4 files and figures are not displayed.

How can I see them?

Is there any functional difference between free version and professional version?

No functional difference.

All you are paying for is direct support from Piriform developers instead of this user forum.

Please advise :-

Your version of Windows,

Whether you are recovering from FAT32 or NTFS formatted drive.

I am using windows XP SP3 and NTFS formatted drive..

Regret I cannot help you further, but your information may be of use to those who can.
