Have you exported your private keys before you reinstalled the OS? If not, you have to crack it. I did it once with Win2K encrypted files and it was quite fast (minutes), but since then the encryption scheme for EFS was upgraded.

You can only read the encrypted files from the installation it was made on or you will need to crack it. If you could uncrypted the file from another OS by simply taking over ownership it is not called encryption.
