Recover files from formatted SD-card.

[steam]

I have a digital HD video cam Panasonic HDC-SD90.
Accidently I formatted the SD-card and some very important videos was lost.
I have tried several recover softwares like Photorec, Cardrecovery, Recuva, Stellar and some others but no luck.
Funny thing is that I have recovered videos that is several weeks and months old but none of the videos I took the latest.
Are the files lost forever or is there a powerful recover tool that can recover them?
I have not used th card since I formatted it so the files should be there I think.
I need your help badly.
