Updating Crysis V1.0 to V1.1 "Problems"

[KillaBot]

i had the same problem first.

if you have modiefied any fieles of the game (enabled dx10 in xp / use a crack / enabled cheats etc) the update tries to read from dvd, but wont find the needed file, because it doesnt exist.

the only way to fix this is to uninstall the game, delete the games folder if there are some rests and then reinstall it. then you can patch it. after that you can remodify files if needed (cheats, dx 10 etc)
(found it somewhere in the ea forums when i had the problem)

hope that helps
