probliem in decryption

I encrypted my ‘E’ drive with NTFS in XP SP2.

Rcently I formatted my primary partition and freshly installed XP SP2.Now when i try to open any file in my E drive i receive the message:

“windows can’t access the specified evice or path or file.You may not have appropriate permissions to access the item.”

thereby blocking me,the administrator myself.I think i’ve lost my encryption certificate after formating my C drive.I don’t have any idea to decrypt my drive,leaving me in a dilemma.

If anyone has the procedure to decrypt my drive or any decryption softwares and tools,please help me.I’m in dire need of the data stored in that drive.
