Hi John,
I am sorry for the long delay in replying :)

Regarding the firewall, I am not 100% sure that this is the root of
your problem and more over I am not familiar with PC
Tools Firewall Plus One simple test to see if this causes
the problem, just shut down all firewalls completely including the
windows firewall (not just minimizing it!) and if necessary use alt-
ctrl-del to force it. Then when this is done, run mathematica and do a
simple calculation. If mathematica now works, then your firewall was
the root of the problem and you have to add an exception for
mathematica (see the documentation for your firewall to see how to do

If this fails, I am afraid I have no more clues to help and you should
ask Wolfram support for more help :(

Cheers and good luck!
