removing ntfs compression attribute

I have googled, searched this site, you name it. I have a program called cryptainer LE, that got compressed once while doing a disk cleanup. Now when I try to access it I get the error message," the special volume has been compressed on an NTFS partition. This is not supported, please remove the compression attribute." Well dang it I have tried but can't get it. I have searched the software's faq's, microsoft website, many other places. I have Win XP Home Edition, on a Compaq Presario notebook. Help please anyone. The program creates a volume that can only be accessed by password, I know my password so that isn't my problem. Thanks in advance to anyone that can help.

Take a look at this and see if it helps at all. If not I'll see what else I can find.
