Black/White screen: Take 2

[Jacktheripperman]

I used to play Graal all the time.. like literally a year ago, perhaps a year and a half. But i moved on to WoW at some point to join some friends and its been fun, but sometimes i just need a break and i missed the old school Graal. I installed everything and got my old account and password n everything, PERFECT WOOT! And then... Dun dun dun... So to get to the point...

I have the same problem as a guy from a thread below... i think.
When i try to log onto Grall the graal screen goes white OR black, it alternates, and then after oh... 15 seconds it gives me a message that reads "The connection could not be established" Now, i know i have the internet cause... well im here arent i? and i know my account is working and i used the correct username and password. My firewall asked me when i first tried to connect if i wanted to allow it, and i clicked "yes, save this answer" but still nothing. Now... i saw something about like 100 something ports you can open... but am i seriously going to have to sit there and manually open 100 something ports???
Thanks in advance... i opened a ticker at cyberjour or however its spelled and got no response whatsoever, so anybody got an idea?
Oh and i have windows XP
