it actually happened to me and i found out that my game can't be patched to 1.4 because the "game.dat" file on the the zero hour folder was a crack. Try reinstalling zero hour and don't copy the "game.dat" on the cd/dvd but copy the "game.exe". Patch the game to 1.4 then install shockwave... it should work but you should have the cd 1/dvd on your cd/dvd drive.
