Questions on using NO-CD/DVD or crack

[wolfsrain]

Unfortunately you won't be able to play online if you use a crack. A mini-image it's recommended for online use, but not a crack. Most of today's games have a file integrity check, and the crack is treated as a modified file and an attempt to cheat. So using a crack for online games it's not a wise idea.
If the game it's single player only, you can use a crack with no problems, but as for online games, you need the original CD/DVD in drive(or a mini-image mounted in Daemon Tools, as the mini-image provides a no-CD solution, without overwritting any of the original files).
