Can't import req to Pki

[intrud3r]

Hi all, can't import client.req file in CA.
Subject:
After this command:
./easyrsa import-req /home/ca/client.req UNIQUE_SHORT_FILE_NAME
i've got this message:

Easy-RSA error:

The input file does not appear to be a certificate request. Aborting import.
Offending file: /home/ca/client.req

But i had done it with server.req !
