pgp:generate key (3071:too many user IDs specified)

Hi there,

I've just installed PGP commandline 10.0.

I have entered the license info and then I created a new keypair with the command 

pgp --gen-key "NAME <MAIL@AAA.COM>" --key-type rsa --encryption-bits 2048 --signing-bits 2048 --passphrase 'SOMEWORD'

I've repeated this process several times because I'm creating a manual for another department.

In between I've used pgp --remove-key-pair NAME --force to delete the existing keypair.

Suddently I came to a point where I can't create a new keypair anymore, I see the following error message:

pgp:generate key (3071:too many user IDs specified)

What should I do?
