Finally I have found a solution for my problem wich was
"Waiting for region handshake/Login packet never received"
The main problem was that my router blocked the internets to SL.
In this case, the brand of the router is as follows:
U.S. Robotics Broadband Router with USB Printer Server (Model # USR8001, Version V1.1)
Right, if you have this brand or not, log in to your router and look for the DMZ Host.
This function allows a direct connection between the internets and your computer.
Set the DMZ Host to your computers' internal IP adress, ie. 192.186.1.5 or 10.0.0.34
Save the settings and start SL again.
In my case it works, hope it works for you too.
(now how to fix the renderproblems with my ATI RADEON 9000/9100 PRO IGP...)
