Problems with import

[Almudena Hernández]

        Hi!
                I have the 1.13 version,over a Red Hat Linux 7.2. I've just 
created the repository, with the command cvs -d /opt/web init, and was ok, but 
every time I try to import one new module, with the command:
                         cvs import -m "primer version" webRF cvsuser inicio
        It says:
                cvs [import aborted]: attempt to import the repository
        Can someone tell me why?
        Thanks in regards!
