transfer key pair from pgp command line to pgp desktop ?

Hello,

I created a key pair using PGP command line 9 on machine A.

I need to copy this key to a  machine  B, which has PGP desktop.

On machine A, i can export the key pair, like this : pgp --export-key-pair 0xxxxxx --output c:\key.asc

Then on Machine B, I try :"file\import personal certificate" but nothing happens.

Also, do i need to reset the passphrase ?

Thanks,Peter
