problem with The Battle for Middleearth II
 

the problem is that in single play everything destroy after 2 min i can't complete first mission .but in skrimish it works fine.

what's wrong?

Probably improper crack. Try with the original DVD. If you still have problems, contact the publisher; if it works fine, use it until a proper crack is released. (Or create a backup or full image of the DVD; read the FAQ on how.)

Wasn't this because of a bad/stolen serial ?
I dunno exactly, but it's possible that the game connects with any EA server trying to validate the serial.
I never had such problem tho so I cant assure you that this is exactly the cause :)

i think it was incorrect registry entry, i've got some problem as you with armageddon effect, may be we wait another patch

What I heard is EA released a beta to the warez scene as a clone image to catch people out.

They are following the same steps Valve did with HL2. Catch people at it and remove them when they finally gave up on their illegal game and bought a new one and have their accounts barred :P Which was pretty low of them.

I think EA is doing the same with serials incase anyone who managed to get a keygenerator would kill serials generated left right and centre.
