PGP Email not encrypting; can't find key

I have a PGP open standard public key that I can't encrypt to.  All low hanging fruit has been explored, i.e., the key has been signed by me and is verified.  I've attached the key here.  I was able to encrypt to this key with another PGP service that is different then the third party program used to create the key with no problems. 

Any help is greatly appreciated.
