Why Wont This Work!!!

[LilGuido]

i recently got neverwinter nights. i downloaded an installed all the patches. i found the the 1.65 no cd crack. i replaced the nwmain.exe file and when i try to run the game it doesnt run. nothing happens at all. the launcher(with the update, config, options, play meny) closes and then im just staring at my desktop. i check the task manager and i see nwmain.exe sitting there taking up 11,000whateve kb. its there. its doing something, why isnt it running. this is the exact same thing that happened to me when i tried the crack for kotor2. is this a common thing for bioware games, am i doing something wrong. do i have to mount an image file. wut can i possibly do. ive used cracks countless times and this is the only game i cant get to work(including kotor2). this is pissing me off to no end. is there anyone that can help
