Same thing occurs, Game Crashes, what if I don't use Crackshield?
Restart your computer first, then try this.
Upon login it will demand you run crackshield, and then wait until you've run it and clicked retry.
If this happened, run it and click retry. If this works, close game, re-enable data mods from above, run game again.
Depending on OS and how up to date hackshield is, you may or may not experience issues.
Since you say it won't run at all, my first guess is that it's OS related.
Could easily be wrong, but that is my go-to when people say it doesn't start.
