Fail to connect to Verification Server?

Re download, and de frag your comp, that will do the trick.

It means you are banned from combat arms, use cbl site to confirm.

What do you mean by "d frag your com"?
Thanks

The account is not banned, cause i can access it without hacks but once i add the .dll file it fails to connect to the server

Yes, its banned..

Defraging you computer is when you clean up any of your drives such as a :HDD

Steps on how to defrag your drives:

1: Navigate to Windows start menu
2: Search "Disk Defragmenter"
3: first select a disk then select "analyze disk"
4: once that is complete select " defragment disk"

That's all.

*note: if you use your computer a lot I would recommend Configuring a schedule for it to run every once and a while.
