Problem with ports

I installed FreeBSD latest version 32 bit and during the installation process I choose to install gnome desktop. But now I have these problems:

1)
installing from the ports I get

Code:
cd: can't cd to /usr/ports
cd: can't cd to /usr/ports/ports-mgmt/portupgrade
cd: can't cd to /usr/ports

2)
Installing from the internet br pkg (I can browse internet so I have an internet connection)

Code:
pkg_add -r gnome2-power-tools
Error: Unable to get [url]ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.2-release/Latest/gnome2-power-tools.tbz:[/url] Syntax error, 
command unrecognized
pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.2-release/Latest/gnome2-power-tools.tbz' by URL

3)
Should add/remove work with FreeBSD

I get this below internal system problem

Code:
The backend exited unexpectedly. This is a serious error as the spawned backend did not complete the pending transaction.
I could not find out what is going on.
 
Also when I check it now cd /usr/ports does not exist. Is it possible at all, also I check in / folder to find any ports folder in nautilus, so I am lost ....
