How did u crack it? With pliers?
I wouldn't mind seeing a cracking video.
monkeynuts actually cracked my Gold Titan for me to go back for a second round of grading at ANACS. He used some grips, with the slab inside a plastic bag to prevent shattered plastic getting everywhere. Crack each corner bit by bit, and slowly prised the slab apart.
As Z says, I used locking grips set at just less than the slab. Emphasis on crack rather than destroy. Less is more. Many small steps rather than one giant leap. Corners, then middles.

Other options I have read about are in a bench vice and then use a hacksaw (take the edges off, you can get away with 3). One of those small electric 'rotary tools' would also do the trick.
Its only the very edges that get bound by the resin
If your gonna do it, always practice with a low value slabbed coin first !! There is always risk associated. Reward has to be clear before doing it, generally an older graded coin.
CGS slabs are far more stubborn than ANACS (far more brittle, so more unpredictable).
