Windows 7: Recover hidden file help needed

I have a problem , I need to recover a hiiden file on a removable drive , I had a system crash last night and had no other choice but to do a system restore.

I am running Windows 7 x64 , I had an important file hidden on a removable drive protected by Free Hide Folder , Free Hide Folder was installed on my main C drive the folder I am looking to recover is on my M drive but when I did a system restore the folder on the M drive was locked and hidden and now after recovering from the crash and reinstalling Free Hide Folder the folder is not shown even though I know it is there just by looking at the disk volume all the other folders that were not protected are there and in tact , there is no backup made for Free Hide Folder .
I have tried "show hidden folders" in both control panel and registry - Does not work
I have also tried "attrib" command and does not work either .
Is there any possible way to recover this file ?

Any help at all will be greatly appreciated .

Thanks richc46 ! DiskDigger worked , it is a bit of nagware if you use the free version but the $15 I spent for the full version was well worth it , I have recovered all my files !

Pheww ! Thats a backup lesson I will not soon forget

Glad thatI could help
