Import MAK comand failes 3090 bad parameter

The documentation for PGP cmd line is really scarce especially for interfacing with PGP Universal KMS.

I'm trying to generate a PGP key locally and have it imported into PGPU in GKM mode

this is the command im running (private info witheld ofcourse):

pgp --auth-username test --auth-passphrase test --usp-server 1.1.1.1 --import-mak --name test@test.com --input C:\test@test.com.asc

and this is the error:

pgp:import MAK (3090:operation failed, bad parameters)
 

I can create MAK on the PGPU no problem I can also send the public key no problem. any ideas on what im doing wrong?
