We recently put in central air in the house. We have only one main
trunk line going down center of the house. The family room is in the
basement (where i spend most of my time). Heres the problem, since we
put the central AC in, in order to cool the main floor to say 80 its
between 60 or 65 in the basement. So upstairs stays too hot and
downstairs too cold. I wrapped the ductwork in the basement with that
tim foil covered insulation and cover all the vents with that
insulation and tape them up yet it is still too cold. Is there any way
to achieve a closer balance between the up and down spaces?

Sounds like an improperly designed installation. Your scenario is a
common complaint. Since it was recently put in I would call the
installing company back and ask them to fix the problem. DO NOT just
block off the vents in the basement. Taken to extremes, this increases
the static pressure on the air handler and can create other problems,
including damage to your system.
