Connection Lost

[Cpl.Dunn]

Hello anyone!

I have this problem with project reality since i installed PR v1.3 ,everytime i join to co-op or a server online the page is loading to the server and then.."Your connection to the server has been lost".I looked through forum and i have seen a lot of players who had this problem ,but i didn't find something that really help me.

My specs:
Windows 7 64bit
AMD Phenom II X4 945-3.00 Ghz
4GB 800 Mhz RAM
ATI RADEON HD 6670-2GB
HDD 660
Resolution 1366x768

Graphic card-it's updated,the same thing with punkbuster .
