Norton UnErase

[Goofy]

I used Norton UnErase to get back some files from my hard disk that I have deleted by mistake.
Well... when I try to re-open that files I cannot view anything.

My files were created with Archicad 6.5 and the extension is PLN
Can someone help me???

Thank you very much

I installed Ontrack EasyRecovery Professional 6.0 but I cannot repair PLN files.

Could someone help me??

Thank you very much
