Folder lock problem!!

[yrana2002]

I've been using folder lock these days to lock some of my files. It asks u to copy all files to a locker folder which it opens. On exiting, the locker folder disappears. once i opened a file attached with an email. Nothing happened but then on, the locker folder displays no icons eventhough in properties, it displays the size of the files in the folder & the no. of files. Hence i'm not able to access the files. Do i have to edit the registry or anything like that?
Comments are welcome!!
