i am using Jass NewGen too. well, have you installed your game with a bought warcraft III CD? may it be that your CD had some scratches while you had installed warcraft? may it be that you have changed anything in the warcraft datas?
Be happy that at least you can buy a disk, xD
In my country just the ROC or TFT costs R$85,00, wich is about US$47,00 if I'm not wrong in my calculations =P Buying directly from blizzard the full pack is US$40,00!
I think leave it for real old news that cannot be sorted the reason we had it in the first place was a server issue that we do not have anymore. I don't want to get rid of the archive just not put anything in it for now until we figure it out more
