I haven't messed with gpg for a while but it seems to me that the message 
was encrypted with the worng key.  In other words for you (Tim) to be able 
to decrypt the message uaing your private key Roger should have encrypted 
it with your public key.  You should not have had to import Rogers keys. 
However if had needed to verify Rogers signature you would need his public 
key(s).
