Command and conquer generals online
 

i have downloaded the online patch and followed the instructions carefully and evrything works but when i try to play online the game checks for updates and downloads them after that the game doesn't lauch again, it gives a "technical error" so i have to un/reinstall the game again ?

i could use some help (please tell me the order of installation and what i should do if the serial # is already taken by a user playing online)

Try downloading the crack for the latest game version - when the game updates, it changes the main exe or game.dat and so you need to download a new crack.

For the serial issue - contact EA Pacific if you suspect someone else is using your cdkey (if you're sure you haven't leaked it).
