Hi, i´m having problems on generals zero hour online game. Last week i played online with no problems, but since now everytime i do the login a message appears saying that my serial is invalid. So, i would like to know if my friends overthere, knows a way to fix this problem (a crack or a serial valid) i apprecciate your help.

If you have a legal copy you will also have a valid key, but if you still can't play online then probably someone else is using your key. In that case I suggest to contact EA.....

Yes, contact EA with some proof of purchasing the game and they may be able to supply you with a new key.
