Use of professional, industrial-grade data recovery software is recommended to retrieve your deleted files. Consumer grade ones are OK too but may have lots of restrictions.
Just make sure you did not HARD-FORMAT (ie. low-level format) your SD card because doing do will permanently erase all files without the possibility of recovery.
Final Data mentioned in #1 is fine, but I don't think it's ever available as trialware. Also, its interface is IMO not very friendly. EasyRecovery Pro is another alternative, but again is out of normal consumer's reach (unless of course if you try peer-to-peer).
Additional information regarding such software has been PMed to you, please check your email.
