Ive had major issues 2 with connection problems.
Ive shouted at CS many times and blamed evrything and everybody but i have figured out (With help from other forums) what it is.

ITS MY ISP !!!!!

They block ports in peak times so i can rarley play between 4-11pm during the week.

If your with Pipex,Tiscalli or a couple of others then there is where the problem lays.

Hope you get it sorted fella
