Encrypt Error - There is no assurance this key belongs to the named user

[Thomas Chitwood]

I am getting this error when trying to encrypt a file using a public key 
generated by PGP Desktop 10.0.2 (Build 13). I am using gpg (GnuPG) 1.4.5. 
I think the error is being caused by the validity setting for this key in 
my keyring which is "validity: unknown".

Two questions:

First, is there a way to set the validity parameter in the version of 
GnuPG I am using.

Second, are there any known incompatibilities between PGP Desktop 10.0.2 
(Build 13) and gpg (GnuPG) 1.4.5?

Thank You in advance for your assistance.
