Login issues

[LOL]

for a few days i'm not able to login to the server anymore,
i get the part for user/pass then it hangs in the screen with the text:
you are currently logging in
please wait a moment.

i've tried several things like deleting  the system folder and let the updater update it,
but without any suc6.

Try to download new .dll   

[LOL]

tried that,
didn't work.
but i'll try something else.

Antivitus or firewall block .dll work.
or bad internet connection
