I've tried install and re-install at least five times, each time with CCleaner registry cleaning. I've even called EA Support Center. They said, that I should turn off antivirus and firewall, emulation programms like Daemon Tools and kill all CPU process not assosiated with System or Local Services. I've tried all of that with no result. This is killing me, because I very like this game, and still can't play by any means.
The funny thing is C&C Generals without Zero Hour works fine. Is it just me, or somebody had similar problem?
