The links I provided you for File Recover by PC Tools is trialware...you'll need to pay for the software in order to utilize the recovery option for this software.
But back to the original problem...when you used the File Recover software...did it find the files you were looking for? If it did...and they are still there...then paying for the software may be the way to go in order to recover your lost files.
Someone else, however, may be able to find a free software program that will accomplish the same type of data recovery you're looking for.
Good luck!
