I had that happen but it had to do with my hood release cable and I had to get it replaced. I highly doubt that is your problem though since obviously it just worked before you took the stock hood off and it's way to coincidental for it to happen.

Make sure there is no crud in the locking mechanism as well, make sure you back down the bump stops (rubber bumpers) in the engine bay that the hood rests on as maybe the design of the CF hood is slightly different (support structure) that the rubber bumps sit on. Just a thought.......
