I have never used the TPM on Windows, Keith - I tend to use it primarily
with Java applications - but, if I understand what I think you did from
your description, you've re-initialized your TPM chip, thereby erasing
and over-writing the (Storage Root) key that could have decrypted the
key(s) that encrypted your files.

I'm sorry to be the bearer of bad news, but I would recommend contacting
Microsoft to see if their process of initializing the TPM, perhaps,
escrowed your storage key(s) by migrating it under a public key from
some Microsoft Migration Authority or something equivalent.  Its a long
shot, but perhaps, its worth pursuing.

Good luck.
