You can only use the Bevel command on closed curves so your cuves are not closed properly. To give an example, just create a circle curve or a square curve or a text curve and then try the Bevel Plus command on that. If it works you'll know your curves are not closed well.
Your not trying to do a Birail are you? Which is in the same menu just a little higher.
...and that is how I saved the world.
