Can't access previously encrypted files

Specs: Windows XP pro
A couple of years ago I backed up some files form my office machine (XP Pro) onto an external HDD. The files were encrypted. Today I tried accessing them and could not. I could not read, copy, move or delete these files, even though it said that I have full access permissions. Every time I tried doing something with the files, I got "access denied".

I suspect that this is happening because encryption was done while my corporate password was different (it changes every 120 days). Can I get access to the data without knowing my old password?

Thanks much!

I am assuming the files were encrypted with NTFS encryption.
This encryption is based on a certificate that is a part of your user account. Changing your password will not be a problem. But if Windows was ever reinstalled since the files were encrypted, then you have a problem. If the computer is a member of a domain the domain admin may be able to recover them. I don't know of any other solution.
