vqadmin and httpd

Hi i`ve got a problem with using vpopmail

Whent i type myhost.mydomain/vpopmail system want`s from me to logon and that`s ok .... but , when i do this all i see is :

---------------------------------------------------------
Access forbidden!
  You don't have permission to access the requested directory. There is either no index document or the directory is read-protected

---------------------------------------------------------

i thought that is a problem with loging but when after i enter login and password i type http://myhost.mydomain/vqadmin/vqadmin.cgi it works i mean it`s showing my username and so but nothing can be done with virtualdomains i can only look what virtual domains are on my computer but can`t add them .
    I`ve done everything as they say on manual but still nothing ....
