I can't land it in the sim worth a crap either. Don't worry about flaring, you just let it hit. It seems weird at first but that's what you gotta do. FWIW I floated on my probationary PC in the sim as well, way past the touchdown zone. They guy got upset but I was like "WTF do you want me to do???". LOL. Don't worry about it. The CRJ-200 is one heck of a hard plane to land, even "by the book". If you don't flare at all it'll hit the nose wheel, if you do it too much you can kiss 5000' of runway goodbye.
