When Login "Timed Out"

[Createzzz]

Hey i complied my Client and everytime when i try to Login i get the message "Timed out" (Yes the Servers are running)

I already used the Search function here but the topic i have found didnt helped me. I already tried the following things:

- Check Firewall (I turned it off and open the Ports for LoginServer and Game Server
- Check Server configuration files 
- Check CheckIPFilter function ( CommunicationInterface.cpp[/i] )
- Check sl.dta
