Q: problems with mail and mac app store

when I try to log in to the Mac app store  get the message:

" your computer could not be verified, please contact support." ( i get the message in dutch)

when making an account in mail or i cloud I get the message:

" there are problems with th communication with icloud"

It is an Imac problem because on my macbookpro everything is oke.

what can i do to set or reset things.
