Are you fowarding it right? Go to the email you want to fwd, and open it. Then click fwd. Then type in the emails you want to forward it to in the 'To:' menu.)
Cc: (carbon copy) is just a way to send the same email to a different person (if you put them in here, they don't know who else you sent it to in your main "To:" box.)
Bcc: (is bi carbon copy, I think) Same as Cc: (not 100% sure), but the person that who's email you put in here can't see anybody else's email you sent it to.
You don't need anything in the Cc: or Bcc: menus, it's optional.
I'm not 100% sure about what they do, but I never use them, and I fwd stuff all the time.
That's pretty much all I can do to help you, if the forwarding doesn't work again, then ,for sure, do contact your provider.
