Same thing has happened with my NXT. It came and went from the wallet, but as long as you can see it on the blockchain, you'll just need to wait until the next time they release an updated wallet that actually works. I started my 2.0 experiment with NXT, but quickly became frustrated, and ended up much happier here with Bitshares. I don't see why they had to build that whole NXT ecosystem from scratch on Java with that clunky passphrase login.
They are slowly making NXT more user friendly, but I still didn't have a good feeling about it and I moved on. Most importantly, they do not have the vision of Bitshares in terms of the products, nor does NXT have anyone with a keen understanding of economics like Bitshares does. Aside from Maidsafe, is there a single worthy investment anywhere in Mastercoin or NXT? They all look like scams, fly-by-night schemes, and assorted trash. I'd trade them all for a snapshot in any one DAC within Bitshares...Oh that's right; I did trade them in all for PTS and AGS already!
One more thing: I love that we know who the Bitshares team is. They're not hiding under some rock using fake names. This is an honest and communicative bunch.
