Well. Long time ago i played in another server. But it wasn't even the same computer. ANd i already played in this server like 2 years ago.
What u mean by unpack?
I Extracted the files as it says to do... and then i clicked on the HelGame file to play.
EDIT:
Oh... the problem was with the Anti-Virus... It was blocking the program... I entered the game now so i guess it's working.
Thank you a lot anyway :)
