I'm hazarding a guess... you probably need to call:

   pubKey.SetPublicElement(point);

after decoding. Decoding does not set the public element automatically.

Or maybe you need to decode with "03" instead of "02". The prefix
affects whether y or p-y is returned from the modular square toot that
solves for y.
