Sorry for my previous post, but I had the 2.4.1 version so I decided to uninstall it and install the 2.5.1, I downloaded the complete version and unpacked it to the desktop, then run one of the .sh files on it, but when I try to go in in some server. I see all th map black and the people are diamods of colors? is there any solution to it?

thanks

It might be either server problem or yours. Can you create local game with bots ? If you can and it runs OK then it's server's problem.

sudo apt-get install libcurl3
