uhh, this will end in a head ache.
For now i can not give a fast help, so i let you a list of things to try:
Borrow a internet of a nieghbor or from a friend. (to check if the problem is a connection problem)
Try to run FH in another computer with you own connection. (to check if the problem is from the computer)
Ask for help to a friend who knows well about computers and networks.
Try if another online games can run, like Impressive Title.
Note: if you can not even download the file i given to you, may be because something is blocking you to download and even to play FH. parental control?, administrative permisions? who owns the computer?
