Question : Windows XP - Encryption Problem

I had some important documents in a folder under My Documents in Windows XP.To Ensure Safety, I Encrypted the Documents by the feature provided by the Windows XP.ie.,I right clicked the folder, then in the Advanced button, I clicked Encrypt then Clicked the Check box, all the Files and Folders and clicked OK.After Encryption the folders and files turned in green color.Until yesterday everything was fine.I was able to view my documents.But today when I tried to open the Document, it shows an error that the user dosen't have the permissions to access the file.Even I tried with the Administrator Account the Same Error occurs.Iam Now unable to decrypt or copy or rename..Blankly Iam unable to do anything except deletion.These are very important documents and I don't have any backup to it.So please help me to retrive those files.

Iam running with Windows XP 80GM Harddisk, 1GM RAM, Pentium 4 Processor with  an Single NTFS Partition.

Please Provide me a better solution to retrive those documents

Thanks
