|NTFS encryption encrypts files with a key that is a part of your account. That key no longer exists. Without that key there is virtually no way to decrypt the files. Creating an account with the same name and password will not recreate the key.|
Windows does make provision for reinstalling the OS and still maintain access to encrypted files but that requires that you backup your encryption key before reinstalling the OS. It is of course too late for that.
Unless you have a backup of those files, and you should, I see little hope of restoring them. You should always have a backup of important files. There are a wide variety of ways data can be lost and you must be prepared. Having a single copy of important files is asking for trouble and sooner or later you will get it.
