Piratebox don't show Main Menu

Hello all,
Today I installed the Pirate Box an my TP-3020.
I used the firmware for OpenWRT from the link of David Arts "[piratebox.aod-rpg.de];
Everything was perfect.
For the Piratbox installation I used this Code:
cd /tmp
opkg update && opkg install [piratebox.aod-rpg.de]
No error messages, I think everything was perfect.

No I tried to install the Kareha Image Board:
/opt/piratebox/bin/timesave.sh /opt/piratebox/conf/piratebox.conf install
I think this was ok

/opt/piratebox/bin/install_piratebox.sh
the answer was:
Usage install_piratebox my_config <part> (with al list of the parts)

then:
/opt/piratebox/conf/piratebox.conf imageboard
with the answere of the system:
-ash: /opt/piratebox/conf/piratebox.conf: Permission denied

now I can connect to the Pirate Box Wireless lan . This is ok
connecting to any website I get a Webpage with three frames.
The first frame show me the Pirateboc Logo and the three points:
1. Learn more...
2. Click button...
3. Browse ...

At the second frame I get an error code, short: can't connect to [piratebox.lan]

The third frame shows
Name: "anonymous" Message:
Color ....
and the Button"send"

after sending a Message nothing happened


Please, can someone help me?

I'm a PirateBox beginner and this is my first Box
