They can be a real pita to get fully on. Grease (which you've obviously already done) and force. A block of wood resting on the race and hit with a mallet will sometimes work. I've read of people heating steel races before fitting them, but I'd be very reluctant to do that with a carbon fork.
I wish more companies would supply split races, like WTB used to. As a last resort I did once hacksaw a split in a crown race. It worked, but it was only on a cheap bike which was used for short shopping trips.
