Yes, unfortunately Line 6 doesn't make them anymore.  They have basically bailed on the Vetta.  Look on ebay or craig's list for one.  You have to find someone who has one but isn't using it, which is of course tough since no one would have bought one unless they wanted to use it.  I hope what happened to you doesn't happen to me.  One thing you might try is to take the Vetta apart and reseat the VDI connections.  Having connections get "loosened" has happened to me before.  Go to Vettaville.nl to see how to take your Vetta apart.
